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.

Articles

Thermoelectric materials comprise a wide range of solid compounds distinguished by their ability to convert thermal and electrical energy.

The price of tellurium, a key component in many thermoelectric materials, has risen in recent years, leading to the search for more cost-effective substitutes. This article presents silicide materials as a cheaper potential alternative.

In recent years, the price of tellurium, a key component in the bestperforming thermoelectric materials, has increased significantly, leading to the question, “Is it economically viable to produce thermoelectric generators on an industrial scale?

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
