· JVASP-10792· KHo2CuS4

KHo2CuS4 is an ternary sulfide compound containing potassium, holmium (a rare-earth element), and copper. This is a research-phase material rather than an established engineering commodity; it belongs to the family of rare-earth metal sulfides, which are typically investigated for their electronic, magnetic, and photonic properties. While not yet deployed in mainstream industrial applications, materials in this compound class are of interest to researchers exploring advanced semiconductors, magnetic devices, and optoelectronic systems where rare-earth doping can enable unique functionality.
