Application
General description
Bismuth(III) telluride (Bi2Te3) is a thermoelectric material, which acts as a topological insulator: a quantum material with an insulating bulky gap and gapless edge. It forms thin films by different techniques, which include chemical method, electrodeposition and molecular jet method.[1][2]
The binary chalcogenide, bismuth(III) telluride occurs as mineral tellurobismuthite in nature. 1-2
