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.

Application

Bi2Te3 can be used for a saturable absorber in a variety of photo-optic applications, which include pulse fiber lasers.
