Ho(CuSe)3

Ho(CuSe)₃ is a ternary semiconductor compound combining holmium, copper, and selenium in a 1:1:3 stoichiometry. This material is primarily of research interest rather than established in commercial production, belonging to the family of rare-earth copper chalcogenides that are being explored for next-generation optoelectronic and thermoelectric applications. The incorporation of holmium provides potential magnetic and rare-earth photonic properties, while the copper-selenium framework offers tunable electronic band structure, making this compound relevant to fundamental studies of layered and mixed-valence semiconductor systems.
