Ho2 Cu2 As4
semiconductor· Ho2 Cu2 As4
Ho₂Cu₂As₄ is a quaternary intermetallic semiconductor compound combining holmium (a rare-earth element), copper, and arsenic in a stoichiometric structure. This material belongs to the class of rare-earth pnictide semiconductors and remains primarily in the research and development phase, with limited commercial deployment. Its potential applications leverage the electronic and magnetic properties arising from rare-earth–transition metal interactions, making it of interest for next-generation thermoelectric devices, magnetic semiconductors, and quantum materials research where unconventional band structures and phonon-scattering mechanisms could offer advantages over conventional semiconductors.
