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 topological insulator, and thus exhibits thickness-dependent physical properties. AEM Deposition specializes in producing high purity Bismuth Telluride (Bi2Te3) Sputtering Targets with the highest possible density. High Purity (99.99%) Bismuth Telluride Sputtering Target with smallest possible average grain sizes can be used for semiconductor, chemical vapor deposition (CVD) and physical vapor deposition (PVD) display and optical applications.
