  • reactor
  • A tellurium containing precursor is provided and introduced into the reactor, which is maintained at a temperature of at least 100° C. Tellurium is deposited on to the substrate through a deposition process to form a thin film on the substrate. (patentsencyclopedia.com)

  • antimony
  • An investment report released last month by Jack Lifton at ResourceInvestor.com says that this fall, Intel and Samsung "will introduce flash memory replacements…that can be used, erased, and used again indefinitely, but, rather than being crystalline silicon technology based, are made from tellurium based glasses composed of germanium, antimony, and tellurium. (blogspot.com)
  • Powder
  • The aim of this study was to evaluate the effect of biofield energy treatment on thermal, physical and atomicproperties of tellurium powder. (peerevaluation.org)
  • The tellurium powder was equally divided in two parts: control and treated (T). Thetreated part was subjected to Mr. Trivedi's biofield energy treatment, whereas the control part was remained untreated.Subsequently, the control and treated samples were characterized using differential scanning calorimetry (DSC),thermogravimetric analysis (TGA), X-ray diffraction (XRD), and Fourier transform infrared (FT-IR) spectroscopy. (peerevaluation.org)
  • Therefore, DSC, TGAand XRD data suggested that Mr. Trivedi's biofield energy treatment has significantly altered the thermal and physicalproperties of tellurium powder. (peerevaluation.org)
  • Results
  • Besides, XRD results exhibited an alterationin lattice parameter, unit cell volume, density, atomic weight and nuclear charge volume of the treated tellurium powderas compared to the control. (peerevaluation.org)
  • cadmium
  • Aug. 3, 2016 - Solar cells based on cadmium and tellurium could move closer to theoretical levels of efficiency because of some sleuthing by researchers at the Department of Energy's Oak Ridge National Laboratory. (eurekalert.org)
  • A team led by Jonathan Poplawsky of the Center for Nanophase Materials Sciences used advanced microscopy techniques to discover efficiency differences of crystalline structures of various mixtures of cadmium, tellurium and selenium. (eurekalert.org)
  • While some of today's solar cells use a blend of cadmium and tellurium to convert light into electricity, adding the optimum amount of selenium in the right places could help increase efficiency from the current mark of about 22 percent to levels approaching the theoretical limit of 30-33 percent. (eurekalert.org)
  • In some instances, adding too much selenium changes the crystalline structure of cadmium-tellurium and dramatically reduces the conversion efficiency. (eurekalert.org)
  • The alloy composition that performed best consisted of approximately 50 percent cadmium, 25 percent tellurium and 25 percent selenium. (eurekalert.org)
  • We have shown that the amount of selenium incorporated into the cadmium-tellurium controls whether the small crystals inside the solar cell form as crystal structure A or crystal structure B," Poplawsky said. (eurekalert.org)
  • This information can be used as a roadmap for solar cell producers to make improved cadmium-tellurium solar cells that use selenium additions, and hopefully increase the overall efficiency. (eurekalert.org)
  • This also makes solar panels composed of cadmium, tellurium and selenium more competitive with other forms of electricity generation. (eurekalert.org)

  • TeO2
  • By 1984, the company Panasonic was working on an erasable optical disk drive containing "tellurium monoxide" (really a mixture of Te and TeO2). (wikipedia.org)
  • elemental
  • A team of researchers have found two bacterial species that produce tellurium oxyanions as respiratory electron acceptors for growth, leaving elemental tellurium in the form of nanoparticles. (usgs.gov)
  • citation needed] Tellurium is sometimes found in its native (i.e., elemental) form, but is more often found as the tellurides of gold such as calaverite and krennerite (two different polymorphs of AuTe2), petzite, Ag3AuTe2, and sylvanite, AgAuTe4. (wikipedia.org)
  • chloride
  • It was supposedly created by the heat decomposition of tellurium sulfoxide in a vacuum, and was shown to react with hydrogen chloride in a 1913 report. (wikipedia.org)
  • TeCl4
  • Alternatively it can be considered as a Te4 tetrahedron with face-capping chlorines and three terminal chlorines per tellurium atom, giving each tellurium atom a distorted octahedral environment TeCl4 is prepared by chlorination of tellurium powder: Te + 2 Cl2 → TeCl4 The reaction is initiated with heat. (wikipedia.org)
  • The reaction of TeCl4 with a THF solution of N(SiMe3)3 gives a well-defined tellurium nitride [Te6N8(TeCl2)4(THF) (wikipedia.org)
  • Earth's
  • This rarity of tellurium in the Earth's crust is not a reflection of its cosmic abundance. (wikipedia.org)
  • Tellurium is more abundant than rubidium in the cosmos, though rubidium is ten thousand times more abundant in the Earth's crust. (wikipedia.org)
  • atomic masses
  • A further thirty artificial radioisotopes of tellurium are known with atomic masses ranging from 105 to 142 and with half-lives of 19 days or less. (wikipedia.org)
  • metals
  • Tellurium, near the bottom of the family, looks and behaves very much like most metals. (encyclopedia.com)
  • Although tellurium is found with gold more often than in uncombined form, it is found even more often combined as tellurides of more common metals (e.g. melonite, NiTe2). (wikipedia.org)
  • oxygen
  • The rarity of tellurium on Earth is thought to be caused by conditions during the formation of the Earth, when the stable form of certain elements, in the absence of oxygen and water, was controlled by the reductive power of free hydrogen. (wikipedia.org)
  • volatile
  • Under this scenario, certain elements that form volatile hydrides, such as tellurium, were severely depleted through evaporation of these hydrides. (wikipedia.org)
