Chromium sesquisulfide (Cr₂S₃) is a transition metal chalcogenide semiconductor compound combining chromium and sulfur in a 2:3 stoichiometric ratio. This material is primarily of research interest for optoelectronic and photocatalytic applications, where its narrow bandgap and layered crystal structure offer potential advantages in light absorption and charge carrier transport compared to conventional wide-bandgap semiconductors. Industrial adoption remains limited, but the material family shows promise in emerging technologies where earth-abundant alternatives to rare-earth semiconductors are sought.
