More info

Bismuth Telluride (Bi2Te3) is a semiconductor that is alloyed with antimony (P-Type Bismuth Telluride) or selenium (N-Type Bismuth Telluride) as a highly efficient thermoelectric material for refrigeration or portable power generation. Topological insulator surface states have been observed in bismuth telluride.
