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. WebBismuth ferrite (BiFeO 3, also commonly referred to as BFO in materials science) is an inorganic chemical compound with perovskite structure and one of the most promising …
