General description

Antimony(III) telluride (Sb2Te3) is a three dimensional topological insulator that can be used as a binary sesquichalogenide. It forms p-type semiconducting films for the formation of thermoelectric materials.
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.

Application

Sb2Te3 in combination with bismuth(III) telluride (Bi2Te3) can form super-lattices, which facilitate the fabrication of devices such as thermoelectric generators.
