· La1 Sb1

LaSb is an intermetallic compound composed of lanthanum and antimony, belonging to the family of rare-earth pnictides with a rock-salt crystal structure. This material is primarily investigated in research contexts for thermoelectric and optoelectronic applications, where its narrow bandgap and high carrier mobility make it a candidate for infrared detection, laser diodes, and solid-state cooling devices. Compared to conventional semiconductors, LaSb offers potential advantages in specialized low-temperature and infrared regimes, though it remains largely a developmental compound rather than a mature production material.
