ErHSe

ErHSe is an erbium hydride selenide ceramic compound combining rare-earth erbium with hydrogen and selenium. This material belongs to the family of rare-earth hydride chalcogenides, which are primarily of research and exploratory interest rather than established industrial commodities. The material is notable within materials science for investigating novel phononic and electronic properties in rare-earth systems, with potential applications in thermoelectric devices, optical materials, or specialized semiconductor research where erbium's photonic properties and the hydride-chalcogenide matrix could offer unique performance windows.
