Antimony Telluride Application

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.
