Sm2 Se1 O2
semiconductor· Sm2 Se1 O2
Sm₂SeO₂ is a rare-earth oxychalcogenide semiconductor compound combining samarium, selenium, and oxygen. This material belongs to an emerging class of mixed-anion semiconductors that are primarily of research interest, explored for their unique electronic and optical properties that differ significantly from conventional binary semiconductors. While not yet widely deployed in commercial applications, oxychalcogenides are investigated for potential use in photovoltaics, photocatalysis, and optoelectronic devices where the combination of ionic and covalent bonding creates favorable band structure characteristics.
