 Sb2Te3. It is a grey crystalline solid with layered structure. Layers consist of two atomic sheets of tin and three atomic sheets of tellurium and are held together by weak van der Waals forces. Sb2Te3 is a narrow-gap semiconductor with a band gap 0.21 eV; it is also a topological insulator, and thus exhibits thickness-dependent physical properties.

Applications:
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.
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 refr
