General description
Cobalt triantimonide (CoSb3) is a thermoelectric (TE) material with a power factor, PF of 30 μW cm−1 and a Seebeck coefficient, S of 200 μV K−1. It is a covalent semiconductor material, which has a body-centered cubic (BCC) structure.
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
Cobalt antimonide is a skutterudite which has been widely studied for its thermoelectric properties. It can be doped with different elements to further increase its thermopower. By varying the dopant element it can be tuned to exhibit either p- or n-type semiconductor properties.
