· KSm2CuS4

KSm2CuS4 is a ternary sulfide semiconductor compound containing potassium, samarium, and copper, representing a rare-earth-transition-metal chalcogenide in the quaternary sulfide family. This material is primarily of research and developmental interest, studied for its potential in optoelectronic and photovoltaic applications where rare-earth dopants and mixed-valence copper sulfides offer tunable electronic band structures and light-absorption properties. The compound's significance lies in exploring new chemistries for solid-state devices rather than established high-volume industrial use.
