Sc2 S4

Sc2S4 is a rare-earth sulfide semiconductor compound composed of scandium and sulfur, belonging to the family of binary chalcogenides with potential for optoelectronic and photonic applications. This material remains largely in the research phase, with investigation focused on its electronic band structure and luminescent properties for next-generation semiconductor devices. Scandium sulfides are of particular interest in materials science as alternatives to more common semiconductors where rare-earth doping or extreme material stability is advantageous.
