· JVASP-41445· TmCuPbSe3

TmCuPbSe3 is a ternary compound semiconductor composed of thulium, copper, lead, and selenium, representing an emerging materials system in chalcogenide research. This compound belongs to the family of lead-based selenides and is primarily investigated for thermoelectric and photovoltaic applications, where the combination of heavy elements and mixed-valence chemistry can enable favorable charge carrier properties and phonon scattering. As a research-stage material, TmCuPbSe3 is notable for potential use in solid-state thermal energy conversion and infrared optoelectronics, where engineers seek materials with tunable electronic structure and reduced thermal conductivity relative to conventional metallic alternatives.
