La2Se3
semiconductor· La2Se3
La₂Se₃ is a rare-earth lanthanide selenide compound belonging to the family of rare-earth chalcogenides, which are primarily investigated as semiconducting materials in research and exploratory device applications. This material is not yet widely commercialized but is of interest in optoelectronics, thermoelectrics, and solid-state physics research due to the electronic and thermal properties characteristic of rare-earth selenides. Engineers and researchers evaluate La₂Se₃ as a potential alternative to more common semiconductors in niche applications where rare-earth chemistry offers advantages in band-gap tuning, phonon engineering, or high-temperature stability.
