· JVASP-85160· HoCu2S2

HoCu2S2 is a ternary intermetallic sulfide compound containing holmium, copper, and sulfur, representing a rare-earth metal chalcogenide system. This material is primarily of academic and research interest rather than established in high-volume engineering applications; it belongs to a family of rare-earth copper sulfides being investigated for potential thermoelectric, magnetic, and electronic device applications where the combination of lanthanide and transition-metal chemistry can produce unusual electronic properties.
