CoCu2SiS4
metal· JVASP-92980· CoCu2SiS4
CoCu₂SiS₄ is a quaternary sulfide compound combining cobalt, copper, and silicon in a sulfide matrix—a material family of interest for semiconductor and photovoltaic research rather than established commercial use. This compound belongs to the thiospinel or related sulfide structure class, being explored for potential applications in optoelectronic devices, photocatalysis, and energy conversion where sulfide-based semiconductors offer tunable band gaps and earth-abundant elemental composition. As a research-phase material, it represents an alternative to rare-earth or toxic-element semiconductors, though industrial adoption remains limited and engineering data is sparse.
