· La4FeSb2Se10

La4FeSb2Se10 is a quaternary chalcogenide semiconductor compound combining rare-earth (lanthanum), transition metal (iron), and metalloid-chalcogen elements in a layered crystal structure. This is a research-phase material under investigation for thermoelectric and photovoltaic applications, where the combination of low thermal conductivity and tunable electronic properties makes it attractive for energy conversion and solid-state devices that require reduced phonon transport.
