Tin telluride wavelength range. The alloyed material has been used in mid- IR photodetectors and thermoelectric generator. Tin telluride Tin telluride is a compound of tin and tellurium (SnTe); is a IV-VI narrow band gap semiconductor and has direct band gap of 0.18 eV. It is often alloyed with lead to make lead tin telluride, which is used as an infrared detector material. Tin telluride normally forms p-type semiconductor (Extrinsic semiconductor) due to tin vacancies and is a low temperature superconductor. SnTe exists in 3 crystal phases. At Low temperatures, where the concentration of hole carriers is less than 1.5x10 cm ,
