More info

Tin telluride (SnTe) is a compound of tin and tellurium, is an IV-VI narrow bandgap semiconductor, and has a direct bandgap of 0.18 eV. It is often alloyed with lead to make lead tin telluride, which is used as infrared detector material. Heeger Materials offers a selection of over 100 high-purity products, including metals, metal oxides, and metal salts, with 99.999% purity or higher.
