Bismuth telluride (Bi2Te3), also known as bismuth(III) telluride, is a grey solid powder with a crystalline structure in its pure form. While it occurs in nature as the mineral tellurobismuthite, it is typically prepared by heating elemental bismuth and tellurium under vacuum in a muffle furnace.
A natural semiconductor, bismuth telluride is common alloyed with selenium or antimony compounds to produce thermoelectric materials. This, and it’s potential value as a topological insulator or nanoscale material, make up the majority of its commercial and academic interest.
- Thermoelectrical materials. The most common use of bismuth telluride currently is in the production of thermoelectrical alloys.
- Topological insulator. Bismuth telluride is currently one of the most studied materials to show the traits of a topological insulator. This means that the material shows thickness-dependent properties. Thus, high purity bismuth telluride and nanoparticles of bismuth telluride remain of high academic interest.
- Nanostructures. Due to the unique properties bitmush telluride shows at reduced thicknesses, it is of particular interest to researchers working on various nanostructures, such as nanowire and thin films.
