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 a … See more Bismuth telluride is a narrow-gap layered semiconductor with a trigonal unit cell. The valence and conduction band structure can be described as a many-ellipsoidal model with 6 constant-energy ellipsoids that are centered … See more Bismuth telluride is a well-studied topological insulator. Its physical properties have been shown to change at highly reduced … See more • Thermoelectric materials • Thermoelectric effect • Topological insulator See more The mineral form of Bi2Te3 is tellurobismuthite which is moderately rare.
