· Cu12 Sb4 S13

Cu12Sb4S13 is a quaternary sulfide semiconductor compound belonging to the tetrahedrite mineral family, characterized by a complex crystal structure containing copper, antimony, and sulfide components. This material is primarily of research and development interest for thermoelectric energy conversion applications, where its low thermal conductivity combined with reasonable electrical properties make it a candidate for waste heat recovery and power generation devices. Compared to conventional thermoelectric materials, tetrahedrite-class compounds offer the advantage of being composed of earth-abundant, non-toxic elements, making them attractive for sustainable and cost-effective thermoelectric device development.
