Cu2SnPbSe4
metal· JVASP-155392· Cu2SnPbSe4
Cu2SnPbSe4 is a quaternary chalcogenide compound—a dense metallic selenide combining copper, tin, lead, and selenium. This is a research-phase material studied primarily for thermoelectric and optoelectronic applications, where the combination of heavy elements and mixed-valence chemistry can enable unusual transport properties. The material belongs to a family of complex sulfides and selenides being investigated as alternatives to conventional thermoelectrics for waste-heat recovery and as potential absorbers in photovoltaic or infrared-sensitive devices.
