Ba3SnSb2Se8
semiconductor· Ba3SnSb2Se8
Ba3SnSb2Se8 is a quaternary chalcogenide semiconductor compound combining barium, tin, antimony, and selenium in a layered crystal structure. This is a research-stage material being investigated for solid-state thermoelectric and photovoltaic applications, where its low thermal conductivity and moderate band gap make it potentially competitive with established semiconductors in energy conversion devices. The material represents the broader class of complex chalcogenides designed to optimize the thermoelectric figure-of-merit through structural complexity and phonon scattering mechanisms.
