· Cu2 Sn1 Te3

Cu₂SnTe₃ is a ternary semiconductor compound belonging to the chalcogenide family, combining copper, tin, and tellurium elements. This material is primarily of research interest for thermoelectric and optoelectronic applications, where its semiconducting properties enable energy conversion or light detection; it represents an emerging alternative within the broader class of copper-tin-tellurium compounds being investigated to replace lead-based or toxic semiconductor materials in next-generation energy and sensing devices.
