· Cu12 Sb4 Se12

Cu₁₂Sb₄Se₁₂ is a quaternary chalcogenide semiconductor compound belonging to the tetrahedrite mineral family, characterized by a complex crystal structure with mixed-valence copper and antimony cations. This material is primarily of research and development interest for thermoelectric energy conversion applications, where it has shown promise due to its intrinsic low thermal conductivity and moderate electrical conductivity in the temperature range relevant to waste heat recovery. The tetrahedrite family is notable for offering earth-abundant alternatives to lead telluride and bismuth telluride thermoelectrics, making it particularly attractive for cost-sensitive large-scale thermal energy harvesting systems.
