· Ho1 As1

Ho1As1 is a binary intermetallic semiconductor compound composed of holmium and arsenic, belonging to the rare-earth pnictide family of materials. This compound is primarily of research and experimental interest, studied for its electronic and magnetic properties that arise from the 4f electrons of holmium combined with the covalent bonding environment of arsenic. Ho1As1 and related rare-earth arsenides are investigated for potential applications in thermoelectric devices, magnetic sensors, and specialty optoelectronic components where the coupling between magnetism and electronic structure can be exploited.
