Bismuth telluride

Bismuth telluride (Bi2Te3) is a gray powder that is a compound of bismuth and tellurium also known as bismuth(III) telluride. It is a semiconductor which, when alloyed with antimony or selenium is an efficient thermoelectric material for refrigeration or portable power generation. Bi2Te3 is also known to be a topological insulator, and thus exhibits many thickness-dependent physical properties.
