LaSb is a rare-earth antimonide compound semiconductor composed of lanthanum and antimony, belonging to the family of semimetallic intermetallic compounds. It is primarily of research interest for thermoelectric and low-temperature transport applications, where its electronic band structure and phonon scattering properties make it relevant for cryogenic devices and specialized heat-to-electricity conversion systems. While not widely commercialized in mainstream applications, LaSb and similar rare-earth pnictides are studied as candidates for high-performance thermoelectric materials and quantum transport research, offering potential advantages over conventional semiconductors in extreme low-temperature and high-field environments.
