CuSmSe2
semiconductor· CuSmSe2
CuSmSe₂ is a ternary copper-based semiconductor compound combining copper, samarium, and selenium in a layered or complex crystal structure. This material belongs to the family of rare-earth-containing chalcogenides and remains primarily in the research phase, investigated for its electronic and optical properties that could enable narrow-bandgap semiconducting behavior. Interest in this compound stems from potential applications in thermoelectric energy conversion and infrared optoelectronics, where rare-earth dopants or incorporation can modify carrier transport and optical response compared to binary copper selenides.
