· K2Au2Sn2Se6

K2Au2Sn2Se6 is a quaternary semiconductor compound combining potassium, gold, tin, and selenium in a layered or mixed-valence crystal structure. This is a research-phase material primarily studied for its potential in thermoelectric and optoelectronic applications, as the combination of heavy elements (Au, Sn) with chalcogenide bonding (Se) can produce favorable electronic and phonon transport properties for energy conversion or light-emitting devices.
