TL;DR: In this article, the electrical properties of the mercury cadmium telluride semiconductor material grown by the molecular beam epitaxy are reviewed, and the doping effects linked to the growth conditions, as well as the influence of indium or lithium incorporation are discussed.
Abstract: The electrical properties of the mercury cadmium telluride semiconductor material grown by the molecular‐beam epitaxy are reviewed. The doping effects linked to the growth conditions, as well as the influence of indium or lithium incorporation are discussed. The results on doping by silicon, arsenic, and antimony are presented. It will be shown that all the impurities studied interact primarily with the metal site. It will confirm that the growth occurs under very rich tellurium conditions.

TL;DR: In this paper, it was shown that antimony(III) compounds are biomethylated by Scopulariopsis brevicaulis under aerobic-only growth conditions.
Abstract: Cultures of the fungus Scopulariopsis brevicaulis were grown in antimony-rich media. Although volatile compounds of other elements were readily detected in the culture headspace, volatile antimony compounds were formed irreproducibly and at only ultratrace levels. In order to monitor the media for nonvolatile methylantimony compounds, a method of sample preparation was developed, based on solid-phase extraction. This enabled the separation of large quantities of soluble inorganic antimony species from trace amounts of organoantimony compounds before speciation by HG–GC–AAS. By this methodology methylated antimony compounds were detected at concentrations of 0.8– 7.1 µg Sbl−1 in all media in which S. brevicaulis was grown in the presence of antimony(III) compounds. These methylantimony species were not detected in any of the nonliving or medium-only controls. Methylated compounds were not detected where S. brevicaulis was grown in the presence of antimony(V) compounds. This is the first study to show that antimony(III) compounds are biomethylated by S. brevicaulis under aerobic-only growth conditions. Copyright © 1998 John Wiley & Sons, Ltd.

TL;DR: Germanium, tellurium, and antimony precursors are usefully employed to form germanium-, antimony, and/or antimony-containing films, such as films of GeTe as discussed by the authors.
Abstract: Germanium, tellurium, and/or antimony precursors are usefully employed to form germanium-, tellurium- and/or antimony-containing films, such as films of GeTe, GST, and thermoelectric germanium-containing films. Processes for using these precursors to form amorphous films are also described. Further described is the use of [{nBuC(iPrN) 2 } 2 Ge] or Ge butyl amidinate to form GeTe smooth amorphous films for phase change memory applications.

TL;DR: In this paper, the effect of strontium, antimony and phosphorus on the nucleation and growth mode of the eutectic in hypoeutective Al-10 mass%Si alloys has been investigated by electron back-scattering diffraction (EBSD) mapping.
Abstract: The effect of strontium (Sr), antimony (Sb) and phosphorus (P) on nucleation and growth mode of the eutectic in hypoeutectic Al-10 mass%Si alloys has been investigated by electron back-scattering diffraction (EBSD) mapping. Specimens were prepared from a hypoeutectic Al-10 mass%Si base alloy, adding different levels of strontium, antimony and phosphorus for modification of eutectic silicon. By comparing the orientation of the aluminium in the eutectic to that of the surrounding primary aluminium dendrites, the solidification mode of the eutectic could be determined. The results of these studies show that the eutectic nucleation mode, and subsequent growth mode, is strongly dependent on additive elements. The EBSD mapping results indicate that the eutectic grew from the primary phase in unmodified and phosphorus-containing alloys. When the eutectic was modified by strontium or antimony, eutectic grains nucleated and grew separately from the primary dendrites.
