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.

Generally, Pb is alloyed with SnTe in order to access interesting optical and electronic properties, In addition, as a result of Quantum confinement, the bandgap of the SnTe increases beyond the bulk bandgap, covering the mid-IR wavelength range. The alloyed material has been used in mid- IR photodetectors and thermoelectric generators.
