KCaEr2CuS5
metal· JVASP-145308· KCaEr2CuS5
KCaEr2CuS5 is an experimental ternary sulfide compound combining rare-earth (erbium), alkali-earth (calcium), and transition metal (copper) elements. This material belongs to the family of multinary metal sulfides, which are primarily investigated in solid-state chemistry and materials research for their potential electronic and photonic properties rather than established commercial applications. Research interest in such compounds typically focuses on thermoelectric performance, photocatalysis, or optical applications in laboratory-scale development.
