Bismuth telluride (Bi2Te3) is a gray or black hexagonal platelet with a metallic luster or gray powder. It is an alloy of two metallic elements (Bismuth and tellurium), also known as Bismuth (III) telluride. When alloyed with antimony or selenium, it is a semiconductor that is an efficient thermoelectric material for refrigeration or portable power generation. Topologically protected surface states have been observed in Bismuth telluride. Bismuth telluride and its alloys are unique materials. Th
