CuBiSe2

CuBiSe₂ is a ternary compound semiconductor composed of copper, bismuth, and selenium, belonging to the family of chalcogenide materials. This material is primarily of research interest for thermoelectric applications and optoelectronic devices, where the combination of elements offers potential for tunable electrical and thermal properties. Engineers would consider CuBiSe₂ as an experimental alternative to traditional thermoelectric materials in specialized cooling or waste-heat recovery systems, though it remains largely in the development phase with limited commercial deployment compared to established bismuth telluride or lead telluride thermoelectrics.
