· Sm6 Cu2 Ge2 Se14

Sm₆Cu₂Ge₂Se₁₄ is a rare-earth-containing chalcogenide semiconductor compound combining samarium, copper, germanium, and selenium elements. This material belongs to the family of complex chalcogenide semiconductors, which are primarily investigated in research settings for thermoelectric and photonic applications due to their tunable band structures and low lattice thermal conductivity. The compound is notable for its potential in solid-state energy conversion and next-generation optoelectronic devices, though it remains largely in the developmental phase rather than established industrial production.
