Antimony Telluride Powder 99.99%
Antimony telluride is an inorganic compound with the chemical formula Sb2Te3. It is a grey crystalline solidwith layered structure. Layers consist of two atomic sheets of antimony and three atomic sheets of tellurium and are held together by weak van der Waals forces. Like other binarychalcogenides of antimony and bismuth, Sb2Te3 has been investigated for its semiconductor properties. It can be transformed into both n-type and p-typesemiconductors by dopingwith an appropriate dopant.
