Ca2 S8 Sm4
semiconductor· Ca2 S8 Sm4
Ca₂S₈Sm₄ is a rare-earth sulfide semiconductor compound combining calcium, sulfur, and samarium in a mixed-valence structure. This material belongs to the family of lanthanide chalcogenides, which are primarily investigated in research settings for their optical, electronic, and luminescent properties rather than established industrial production. The compound's potential applications leverage rare-earth semiconductors' capacity for photon emission and electronic control, making it of interest in emerging technologies, though it remains largely in the experimental phase compared to conventional semiconductors.
