Sm2 Cu2 Se2 O2
semiconductor· Sm2 Cu2 Se2 O2
Sm₂Cu₂Se₂O₂ is a mixed-valence semiconductor compound combining rare-earth (samarium), transition metal (copper), and chalcogenide/oxide elements. This is an experimental research material rather than a commercial product, belonging to the family of rare-earth copper selenides and oxides being investigated for electronic and photonic applications where unconventional band structures and mixed-metal coupling could offer advantages.
