Electrically excitable normal rat kidney fibroblasts: A new model system for cell-semiconductor hybrids. (1/426)

In testing various designs of cell-semiconductor hybrids, the choice of a suitable type of electrically excitable cell is crucial. Here normal rat kidney (NRK) fibroblasts are presented as a cell line, easily maintained in culture, that may substitute for heart or nerve cells in many experiments. Like heart muscle cells, NRK fibroblasts form electrically coupled confluent cell layers, in which propagating action potentials are spontaneously generated. These, however, are not associated with mechanical disturbances. Here we compare heart muscle cells and NRK fibroblasts with respect to action potential waveform, morphology, and substrate adhesion profile, using the whole-cell variant of the patch-clamp technique, atomic force microscopy (AFM), and reflection interference contrast microscopy (RICM), respectively. Our results clearly demonstrate that NRK fibroblasts should provide a highly suitable test system for investigating the signal transfer between electrically excitable cells and extracellular detectors, available at a minimum cost and effort for the experimenters.  (+info)

Can subretinal microphotodiodes successfully replace degenerated photoreceptors? (2/426)

The idea of implanting microphotodiode arrays as visual prostheses has aroused controversy on its feasibility from the moment it appeared in print. We now present results which basically support the concept of replacing damaged photoreceptors with subretinally implanted stimulation devices. Network activity in degenerated rat retinae could be modulated through local electrical stimulation in vitro. We also investigated the long term stability and biocompatibility of the subretinal implants and their impact on retinal physiology in rats. Ganzfeld electroretinograms and histology showed no significant side effect of subretinal implants on retinal function or the architecture of the inner retina.  (+info)

Actin motion on microlithographically functionalized myosin surfaces and tracks. (3/426)

High-resolution e-beam patterning exposure of the surface of poly[(tert-butyl-methacrylate)-co-(methyl methacrylate)]-a common e-beam and deep-UV resist used in semiconductor microlithography-induced sharp changes in the surface hydrophobicity. These differences in hydrophobicity resulted in the selective attachment of heavy meromyosin to hydrophobic, unexposed surfaces. The movement of the actin filaments on myosin-rich and myosin-poor surfaces was statistically characterized in terms of velocity, acceleration, and angle of movement. The actin filaments have a smooth motion on myosin-rich surfaces and an uneven motion on myosin-poor surfaces. Interestingly, an excess of myosin sites has a slowing, albeit mild effect on the motion of the actin filaments. It was also found that the myosin-rich/myosin-poor boundary has an alignment-enforcement effect, especially for the filaments approaching the border from the myosin-rich side. Based on these results, we discuss the feasibility of building purposefully designed molecular motor arrays and the testing of the hypotheses regarding the functioning of the molecular motors.  (+info)

Where the chips fall: environmental health in the semiconductor industry. (4/426)

Three recent lawsuits are focusing public attention on the environmental and occupational health effects of the world's largest and fastest growing manufacturing sector-the $150 billion semiconductor industry. The suits allege that exposure to toxic chemicals in semiconductor manufacturing plants led to adverse health effects such as miscarriage and cancer among workers. To manufacture computer components, the semiconductor industry uses large amounts of hazardous chemicals including hydrochloric acid, toxic metals and gases, and volatile solvents. Little is known about the long-term health consequences of exposure to chemicals by semiconductor workers. According to industry critics, the semiconductor industry also adversely impacts the environment, causing groundwater and air pollution and generating toxic waste as a by-product of the semiconductor manufacturing process. In contrast, the U.S. Bureau of Statistics shows the semiconductor industry as having a worker illness rate of about one-third of the average of all manufacturers, and advocates defend the industry, pointing to recent research collaborations and product replacement as proof that semiconductor manufacturers adequately protect both their employees and the environment.  (+info)

Electrospray mass spectrometry of semiconductor nanoclusters: comparative analysis of positive and negative ion mode. (5/426)

There has been a substantial growth in the application of mass spectrometry (MS) methods for the analysis of inorganic materials, due to the inherent sensitivity of mass spectrometry ionization to the specific composition and structure of the analyzed materials. To date, few mass spectrometry studies have focused on metal-chalcogenide materials, an important class of semiconductor materials at the nanoscale, that exhibit interesting optical and electronic properties as a function of size. In this study, we report the application of a correlated electrospray mass spectrometry (ESMS) study between negative-ion and positive-ion mode under low-cone voltage to probe size, composition, and stability of metal-chalcogenide materials at the <1 nm scale. This correlation approach provides insight into the ionization behavior and thermodynamic stability of clusters in the <1.0 nm size domain of the form [Zn4(SPh)10][Me4N]2, [Cd4(SPh)10][Me4N]2, [E4Zn10(SPh)16][Me4N]4, [E4Cd10(SPh)16][Me4N]4 (E = S, Se). It is demonstrated that application of low-cone voltage ESMS can be a useful technique for the rapid analysis of intact solid state nanomaterials when both negative and positive ionic modes are analyzed, with a potential for extrapolation to other classes of nanoscale materials.  (+info)

Semiconductor camera for detection of small tumors. (6/426)

Early detection of small tumors (approximately 3 mm) with only a moderate uptake ratio is often difficult because of poor statistics and a small signal-to-background ratio. The detection capability of a germanium semiconductor camera is analyzed to show that a very large number of counts is required even when the spatial resolution is matched to the size of the tumor. A potential enhancement of statistics using the tissue-scattered gamma rays is discussed based on the superior energy resolution of the semiconductor.  (+info)

Resonant electron scattering by defects in single-walled carbon nanotubes. (7/426)

We report the characterization of defects in individual metallic single-walled carbon nanotubes by transport measurements and scanned gate microscopy. A sizable fraction of metallic nanotubes grown by chemical vapor deposition exhibits strongly gate voltage-dependent resistance at room temperature. Scanned gate measurements reveal that this behavior originates from resonant electron scattering by defects in the nanotube as the Fermi level is varied by the gate voltage. The reflection coefficient at the peak of a scattering resonance was determined to be about 0.5 at room temperature. An intratube quantum dot device formed by two defects is demonstrated by low-temperature transport measurements.  (+info)

Colloidal nanocrystal shape and size control: the case of cobalt. (8/426)

We show that a relatively simple approach for controlling the colloidal synthesis of anisotropic cadmium selenide semiconductor nanorods can be extended to the size-controlled preparation of magnetic cobalt nanorods as well as spherically shaped nanocrystals. This approach helps define a minimum feature set needed to separately control the sizes and shapes of nanocrystals. The resulting cobalt nanocrystals produce interesting two- and three-dimensional superstructures, including ribbons of nanorods.  (+info)

Organic semiconductors differ from inorganic counterparts in many ways including optical, electronic, chemical and structural properties. In order to design and model the organic semiconductors, their optical properties like absorption and photoluminescence are required to be characterized. Optical characterization for this class of materials can be done using UV-VIS absorption spectrophotometers and photoluminescence spectrometers. Semiconductor film appearance and morphology can be studied with Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM).

The study presents an ammonia microsensor integrated with a readout circuit on-a-chip fabricated using the commercial 0.18 μm complementary metal oxide semiconductor (CMOS) process. The integrated sensor chip consists of a heater, an ammonia sensor and a readout circuit. The ammonia sensor is constructed by a sensitive film and the interdigitated electrodes. The sensitive film is zirconium dioxide that is coated on the interdigitated electrodes. The heater is used to provide a working temperature to the sensitive film. A post-process is employed to remove the sacrificial layer and to coat zirconium dioxide on the sensor. When the sensitive film adsorbs or desorbs ammonia gas, the sensor produces a change in resistance. The readout circuit converts the resistance variation of the sensor into the output voltage. The experiments show that the integrated ammonia sensor has a sensitivity of 4.1 mV/ppm.

To quote Shakespeare, A rose by any other name would smell as sweet- however, the roses in my photo are not true roses at all. These miniature roses are made from organic semiconductor crystals. They are approximately 100 microns in diameter, which is the width of a human hair. While these crystals can reflect any color of light, I have colored them red to increase the contrast and enhance the imagination. My research focuses on understanding the crystal growth of organic semiconductors. While most semiconductor materials are inorganic, such as silicon, the compounds I work with offer an organic alternative. Organic semiconductors, if used effectively, offer several benefits such as flexible electronic applications and low energy manufacturing compared to silicon wafers. Before organic semiconductors can be used industrially, the underlying crystallization mechanism must be understood. While the image shown here would not make an effective electronic device, the rose-shape of these crystals ...

This study investigated the association between the risk for spontaneous abortions and the job type of female semiconductor workers to assess their reproductive health. The risk for spontaneous abortion for female semiconductor workers was not significantly higher for FAB and PKG workers than for clerical workers according to their job held longest. However, when the analysis was stratified for the year of conception, we found significantly higher odds for spontaneous abortions (OR 2.21, 95% CI: 1.01-4.81) in PKG workers than clerical workers when the pregnancy occurred prior to 2008.. In this study, the spontaneous abortion rates for FAB and PKG workers were 12.6% and 14.5%, respectively; these were higher than the rate of 11.1% found in clerical workers. These spontaneous abortion rates for female workers involved in semiconductor production were higher than the spontaneous abortion rate of 11.1% reported for Korean domestic 15- to 44-year-old married women [18].

A general predictive method based on Canonical Correlation Analysis (CCA) is developed to identify globally correlated process modes that are responsible for the spatial variability in deep nanoscale semiconductor manufacturing. This multivariate statistical method overcomes the limitations of ordinary multiple linear regression technique by introducing canonical variates with certain properties which allow us to construct a transfer matrix to relate the predictand vector to the predictor vector directly. Principal Component Analysis (PCA), another multivariate statistical technique, is introduced to find the orthogonal modes that explain the larger fraction of the total process variations. We also discuss the constraint of sample number in CCA and propose using the leading principal components (PCAs) to replace the original raw data in correlation analysis ...

An As-exposed group (n = 427) and a control group (n = 91) were included. The As-exposure group (n = 427) included 149 maintenance staff members and 278 production staff members representing high As exposure and low As exposure, respectively. The control group included 91 administrative staff members with no or minimal As exposure. An occupational exposure assessment was conducted to assess personal As exposure by measuring As concentrations in urine, hair, and fingernails of the subjects. Urinary As(III), As(V), monomethylarsonic (MMA), and dimethylarsinic acid (DMA) were quantified to assess an internal dose of inorganic ...
The present invention provides a thin film transistor, wherein the semiconductor channel region is patterned. Gate electrodes 102, gate insulating film 103, source electrodes 104, and drain electrodes 105 are formed on a glass substrate 101. A patterned insulating film is formed thereon, and a part of the film in the region 110 on the gate electrode is removed. An organic semiconductor film is formed thereon by vapor deposition. The organic semiconductor film 107 in the region 110, where the patterned insulating film is removed, becomes a channel region, and is separated from the organic semiconductor film 108 on the patterned insulating film 106. Therefore, the organic semiconductor channel region is patterned to have the same size as the gate electrode. In accordance with the present invention, a thin film transistor, wherein the semiconductor region is patterned precisely, becomes available.

Next, in the method, at least one monolayer layer of passivating material is generated on the pore wall of each of the pores, to passivate the porous semiconductor layer. The one layer of passivating material substantially eliminates dangling bonds and surface states which are associated with the porous semiconductor layer. The resulting passivated porous semiconductor layer exhibits a quantum efficiency of approximately 5 percent. In one embodiment of the

The field effect transistor also includes a source region formed in the back gate region and having the first conduction type, an insulator film formed on the semiconductor substrate and having first and second windows, and a gate electrode covered by the insulator film and located so that a channel is formed in the back gate region. Further, the field effect transistor includes a guard region formed in the semiconductor substrate and located close to the back gate region. The guard region has the second conduction type, and has a first portion located on a first side of the guard region facing the back gate region and a second portion located on a second side opposite
Organic field-effect transistors (OFETs) are potential components for large-area electronics because of their attractive advantages: light weight, cost-effective and large-area processability, flexibility and resonable performance potential. However, the commercialization of OFETs faces several technical obstacles. Low mobility of organic semiconductors limits the current-carrying capacity; high operation voltage restricts their use in many applications; easy degradation in air and instability under electrical stress usually make the lifetime too short to be useful; and contact resistance and contact matching also limit the charge injection to the semiconductor. Many of the above problems relate to interfaces in OFETs. There are two important interfaces in OFETs. The interface between organic semiconductor and the dielectric layer is of crucial importance since it is the location where charge transport in the channel occurs. The other important interface in OFETs is between the semiconductor and the
A flexible organic light emitting diode (FOLED) is a type of organic light-emitting diode (OLED) incorporating a flexible plastic substrate on which the electroluminescent organic semiconductor is deposited. This enables the device to be bent or rolled while still operating. Currently the focus of research in industrial and academic groups, flexible OLEDs form one method of fabricating a rollable display. An OLED emits light due to the electroluminescence of thin films of organic semiconductors approximately 100 nm thick. Regular OLEDs are usually fabricated on a glass substrate, but by replacing glass with a flexible plastic such as polyethylene terephthalate (PET) among others, OLEDs can be made both bendable and lightweight. Such materials may not be suitable for comparable devices based on inorganic semiconductors due to the need for lattice matching and the high temperature fabrication procedure involved. In contrast, flexible OLED devices can be fabricated by deposition of the organic ...

We present a semiconductor quantum optics formalism to study the dynamics of a coherently-driven semiconductor quantum dot interacting with an acoustic phonon bath and a high Q microcavity. A quantum master equation is derived in the polaron frame, where multiphoton and multiphoton effects are included to all orders. As applications of the theory, we study the Mollow triplet of a driven quantum dot in the regime of semiconductor cavity-QED. Pronounced signatures of electron-phonon-photon scattering are observed through excitation-induced dephasing and off-resonant cavity coupling. We also present an effective phonon master in Lindblad form and show example quantum trajectory simulations that help one to understand the features in the Mollow triplet spectra ...
Different III-V semiconductor nanowires are very important for their electrical and optical properties. Diameter of the usual nanowires lies in the 40-100 nm range and with ALE it might be potentially possible to shrink the nanowire diameter to the sub 10 nm range. In this research work we used a system for reactive ion etching, similar to the systems, which are widely used in semiconductor industry for semiconductor device fabrication, for testing ALE possibility in Lund Nano Lab. We demonstrated that with this equipment it is possible to perform ALE and used this process for etching semiconductor horizontal nanowires and to make stamps for nanoimprint lithography. Surprisingly, we found that, due to some specific properties of the ALE process and a hexagonal cross section of nanowires, which we used in our experiments, after ALE each nanowire is split in to two very thin nanowires. We believe that here the inclined nanowire surfaces act as a mask for the etch process and that potentially this ...
An apparatus and method for mass spectrometric determination of contaminant components of a thin oxide surface layer of a semiconductor wafer use a movable mechanical stage to scan and raster a large area of the wafer in a continuous scanning motion. The mass of analyte is greatly increased, resulting in improved sensitivity to trace components in the surface layer by a factor of 10-100 or more. A light beam interferometer is used to determine non-planarity from e.g. warping of the wafer and provide a correction by maintaining a constant separation between the wafer and the extraction plate or adjusting the electrical bias of the wafer relative to the extraction bias.
In accordance with the present invention, a monolithically integrated structure combines a field effect transistor and a Schottky structure in an active area of a semiconductor substrate. The field effect transistor includes a first trench extending into the substrate and substantially filled by conductive material forming a gate electrode of the field effect transistor. A pair of doped source regions are positioned adjacent to and on opposite sides of the trench and inside a doped body region. The Schottky structure includes a pair of adjacent trenches extending into the substrate. Each of the pair of adjacent trenches is substantially filled by a conductive material which is separated from trench side-walls by a thin layer of dielectric. The Schottky structure consumes 2.5% to 5.0% of the active area, and the field effect transistor consumes the remaining portion of the active area.
Osram Opto Semiconductors GmbH of Regensburg, Germany has reported what it claims is the first direct-emitting true green indium gallium nitride (InGaN) laser diode - emitting light at 515nm - with high optical output power (50mW). Osram Opto already offers blue-emitting InGaN laser diodes for commercial applications. But, in the true green 515-535nm wavelength range, efficient high-quality semiconductor lasers have been commercially available only as frequency-doubled versions. Compared with semiconductor lasers based on existing frequency doubling technology, direct-emitting green lasers are more compact, offer greater temperature stability, are easier to control, and have higher modulation capability at several 100MHz, says the firm. Although the new laser is just at the pre-development stage, in the medium term direct-emitting green lasers could therefore replace frequency-doubled lasers for many applications, says Osram Opto. The laboratory prototype achieved optical output power of 50mW ...
In a study published today in Nature Communications, a research team led by Ken Shepard, professor of electrical engineering and biomedical engineering at Columbia Engineering, and Lars Dietrich, assistant professor of biological sciences at Columbia University, has demonstrated that integrated circuit technology, the basis of modern computers and communications devices, can be used for a most unusual application-the study of signaling in bacterial colonies. They have developed a chip based on complementary metal-oxide-semiconductor (CMOS) technology that enables them to electrochemically image the signaling molecules from these colonies spatially and temporally. In effect, they have developed chips that listen to bacteria.. This is an exciting new application for CMOS technology that will provide new insights into how biofilms form, says Shepard. Disrupting biofilm formation has important implications in public health in reducing infection rates.. The researchers, who include PhD students ...
Bipolar transistors are so named because they conduct by using both majority and minority carriers. The bipolar junction transistor, the first type of transistor to be mass-produced, is a combination of two junction diodes, and is formed of either a thin layer of p-type semiconductor sandwiched between two n-type semiconductors (an n-p-n transistor), or a thin layer of n-type semiconductor sandwiched between two p-type semiconductors (a p-n-p transistor). This construction produces two p-n junctions: a base-emitter junction and a base-collector junction, separated by a thin region of semiconductor known as the base region (two junction diodes wired together without sharing an intervening semiconducting region will not make a transistor).. The BJT has three terminals, corresponding to the three layers of semiconductor - an emitter, a base, and a collector. It is useful in amplifiers because the currents at the emitter and collector are controllable by a relatively small base current.[33] In an ...
A method is provided for rapid firing at low temperatures to remove impurities from the semiconductor surface prior to deposition in situ. Advantageously, the short time low temperature process consumes very little thermal expense, making the process suitable for modern high density circuits with shallow junctions. In addition, the throughput is greatly improved by low temperature firing, especially in combination with low temperature plasma cleaning and low temperature wafer loading prior to firing, and deposition at lower temperatures than conventional epitaxial deposition after firing. The process enables epitaxial deposition of a silicon containing layer on a semiconductor surface, in particular epitaxial deposition on a silicon germanium base layer. By using low temperature firing, the silicon germanium base layer can be cleaned to facilitate further epitaxial deposition without relaxing the strained crystal structure of silicon germanium.

Despite their potential use as pixel-switching elements in displays, the bias and light instability of mixed oxide semiconductor thin-film transistors (TFTs) still limit their application to commercial products. Lack of reproducible results due to the sensitivity of the mixed oxides to air exposure and chemical contamination during or after fabrication hinders any progress towards the achievement of stable performance. Consequently, one finds in literature several theories and mechanisms, all justified, but most of them conflict despite being on the same subject matter. In this study, we show that under an optimized fabrication process, which involves the in situ passivation of a mixed oxide semiconductor, we can reduce the bias and light instability of the mixed-oxide semiconductor TFTs by decreasing the semiconductor thickness. We achieve a negligible threshold voltage shift under negative bias combined with light illumination stress when the mixed oxide semiconductor thickness is around three

Zinc oxide (ZnO) is a wide-bandgap material with excellent optical properties for optoelectronics applications. ZnO nanostructures are attractive for research because it is easy to fabricate in single-crystalline form and it has interesting physical properties at the nanoscale. In this paper, we report our successful growth of a p-type ZnO nanorods/n-GaN film heterojunction ultraviolet light-emitting diode (LED). The heterojunction LED shows its advantages over a p-ZnO film/n-GaN film heterojunction. The LED demonstrates a rectifying I-V characteristics with a turn-on voltage of 2.7 V. The ideality factor is 6.5. The existences of interface charges in the interface are the reason for this low turn-on voltage and high ideality factor in the heterojunction. Electroluminescence (EL) spectra of the LED consist of an ultraviolet peak at 378 nm and a broad yellow emission centered at 560 nm. Fitting and comparing EL of the LED with PL of p-ZnO and n-GaN show that p-ZnO contributes more to the EL than ...
Security is a critical aspect in modern circuit design, but research into hardware security at the device level is rare as it requires modification of existing technology nodes. With the increasing challenges facing the semiconductor industry, interest in out-of-the-box security solutions has grown, even if this implies introducing novel materials such as two-dimensional layered semiconductors. Here, we show that high-performance, low-voltage, two-dimensional black phosphorus field-effect transistors (FETs) that have reconfigurable polarities are suitable for hardware security applications. The transistors can be dynamically switched between p-FET and n-FET operation through electrostatic gating and can achieve on-off ratios of 105 and subthreshold swings of 72 mV dec−1 at room temperature. Using the transistors, we create inverters that exhibit gains of 33.3 and are fully functional at a supply voltage of 0.2 V. We also create a security primitive circuit with polymorphic NAND/NOR obfuscation
Semiconductor physics, being one of the largest branches of solid state physics, studies both the fundamental principles of nature and the complexity of its systems. Semiconductors reflect the enormous diversity in phenomena and complexity in nature more vividly than most other physical systems. Clearly, semiconductors form the heart of modern technology, as every chip and every laser in any high tech gadget is made out of them. What renders semiconductors really unique and fascinating, however, is their incredible richness in phenomena, and the enormous range of their physical parameters.. Where, do you think, can we study atoms in extreme conditions that naturally only occur in neutron stars? Where, do you believe, can we watch free quarks - a breakup of the fundamental electrical charge? In semiconductors! In fact, recently Horst Störmer was awarded the nobel prize for finding free fractional charges in a semiconductor called Galliumarsenide. The physical properties of semiconductors can be ...
More PC12 cells adhered to the nanowire squares than to any of the other surfaces, but only 50 percent of the cells grew normally. The other 50 percent spread in all directions, like the cells on the randomly textured surfaces.. This tells us that the actual shape of the surface characteristics influences the behavior of the cells, Bain says. Its a non-chemical way of influencing the interaction between the material and the body. Thats something we can explore as we continue working to develop new biomedical technologies.. The paper, Surface Topography and Chemistry Shape Cellular Behavior on Wide Band-Gap Semiconductors, is published in Acta Biomaterialia. Senior author of the paper is Dr. Albena Ivanisevic, an associate professor of materials science and engineering at NC State and associate professor of the joint biomedical engineering program at NC State and UNC-Chapel Hill. The papers co-authors include Dr. Ramon Collazo, an assistant professor of materials science and engineering ...

We report on the design and fabrication of ZnO-based integrated inverters consisting of normally-on metal-semiconductor field-effect transistors and AgxO Schottky diodes as level shifters. The inverters show high gain values up to 197 at 3 V operating voltage and low uncertainty levels in the range of 0.13 V. The influence of the level shifter and the channel material/thickness on the performance of the inverters has been investigated. Using Zn0.997Mg0.003O for the channel thin film leads to high reproducibility (90%) of the devices. A logic NOR-gate has been implemented showing the possibility to fabricate a complete logic ...
Electronic and photonic materials have greatly changed modern life. Without them, computers, telecommunication systems, compact disc players, video cameras, and all the electronics with which we have become accustomed would not be possible. The study of electronic and photonic materials is a natural bridge between the fields of electrical engineering and material science. Students in electrical engineering will benefit from this minor because they will better understand the materials with which they will design electronic and photonic devices, such as transistors on a computer chip or semiconductor lasers in a compact disc player. Training in the field of electronic and photonic materials requires study of the processing and characterization of these materials to help engineers develop ways to lower cost and improve performance. This knowledge will help prepare students to enter the semiconductor industry or pursue graduate studies.. ...
It is an object to manufacture a highly reliable display device using a thin film transistor having favorable electric characteristics and high reliability as a switching element. In a bottom gate thin film transistor including an amorphous oxide semiconductor, an oxide conductive layer having a crystal region is formed between an oxide semiconductor layer which has been dehydrated or dehydrogenated by heat treatment and each of a source electrode layer and a drain electrode layer which are formed using a metal material. Accordingly, contact resistance between the oxide semiconductor layer and each of the source electrode layer and the drain electrode layer can be reduced; thus, a thin film transistor having favorable electric characteristics and a highly reliable display device using the thin film transistor can be provided.
As part of the JST CREST Program, a team of Takayuki Iwasaki, Mutsuko Hatano and colleagues at the Tokyo Institute of Technology, the Japan Science and Technology Agency (JST) and Toshiharu Makino at the National Institute of Advanced Industrial Science and Technology (AIST) has succeeded in developing a new method for sensing internal electric fields at the interior of operating semiconductor devices.. Semiconductors lie at the heart of many of the electronic devices that govern our daily lives. The proper functioning of semiconductor devices relies on their internally generated electric fields. Being able to measure these fields on the nanoscale is crucial for the development of next-generation electronics, but present techniques have been restricted to measurements of the electric field at a semiconductors surface. The technique exploits the response of an artificially introduced single electron spin to variations in its surrounding electric field, and enabled the researchers to study a ...
A method of forming conductive contacts to drain and source regions of a semiconductor device such as a field effect transistor (FET). A gate structure is formed over a portion of a semiconductor substrate, wherein the gate structure includes: a gate dielectric on a surface of the semiconductor substrate, a conductive gate aligned on the gate dielectric, a silicide layer aligned on the conductive gate, and a silicon nitride cap aligned on the silicide layer. Insulative spacers are formed on sidewalls of the gate structure, and the insulative spacers contact the semiconductor substrate. A drain region and a source region are formed within the semiconductor substrate, wherein a channel region is disposed between the drain region and the source region, and wherein the gate structure is over the channel region. After an insulative region containing a photosensitive material, such as boro-phoso-silicate glass, is formed over the gate structure and the semiconductor substrate, a cavity over the drain region
A laser diode, (LD), injection laser diode (ILD), or diode laser is a semiconductor device similar to a light-emitting diode in which the laser beam is created at the diodes junction. Laser diodes are the most common type of lasers produced, with a wide range of uses that include fiber optic communications, barcode readers, laser pointers, CD/DVD/Blu-ray disc reading/recording, laser printing, laser scanning and light beam illumination. A laser diode is electrically a PIN diode. The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively. While initial diode laser research was conducted on simple P-N diodes, all modern lasers use the double-hetero-structure implementation, where the carriers and the photons are confined in order to maximize their chances for recombination and light generation. Unlike a regular diode, the goal for a laser diode is to recombine all carriers in the I ...
