High-purity and ultra-high purity Antimony Telluride (Sb2Te3) materials are crucial components for the research, development, and production of advanced technologies which require optimum properties, performance, and quality.
Antimony telluride is an inorganic compound with the chemical formula Sb2Te3. As is true of other pnictogen chalcogenide layered materials, it is a grey crystalline solid with a layered structure.
Like other binary chalcogenides of antimony and bismuth, Sb2Te3 has been investigated for its semiconductor properties. It can be transformed into both n-type and p-type semiconductors by doping with an appropriate dopant.
Doping Sb2Te3 with iron introduces multiple Fermi pockets, in contrast to the single-frequency detected for pure Sb2Te3, and results in reduced carrier density and mobility.
Sb2Te3 forms the pseudobinary intermetallic system germanium-antimony-tellurium with germanium telluride, GeTe.
Like bismuth telluride, Bi2Te3, antimony telluride has a large thermoelectric effect and is therefore used in solid-state refrigerators.
