Application

Bi2Se3 is a metal selenide, which can be used for a variety of applications such as solar cells, light emitting diodes (LEDs), and superionic conductor. Its optical properties include a high absorption coefficient larger than 104 cm-1 and a band gap of 0.35 eV.

General description

Bismuth(III) selenide (Bi2Se3) is a semiconducting thermoelectric material with a narrow band gap. It forms thin films by different techniques, which include solution growth, electrodeposition and molecular jet method. It acts as a topological insulator based saturable absorber.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.
