Ho2 Se4
semiconductor· Ho2 Se4
Ho₂Se₄ is a rare-earth selenide semiconductor compound combining holmium and selenium in a 1:2 stoichiometric ratio. This material belongs to the broader family of lanthanide chalcogenides, which are primarily investigated in research contexts for their unique electronic and optical properties arising from f-electron interactions. While not yet established in mainstream commercial applications, Ho₂Se₄ and related holmium selenides are of interest in advanced materials research for potential optoelectronic, thermoelectric, and photovoltaic device applications, particularly where rare-earth dopants or narrow band-gap semiconductors offer advantages over conventional materials.
