Tin telluride is a compound of tin and tellurium (SnTe); it is a semi-metal. 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 due to tin vacancies and is a low temperature superconductor. [3]

Tin telluride is a thermoelectric material. Theoretical studies imply that the n-type performance may be particularly good. [4]
