· Sm1 As1

SmAs (samarium arsenide) is a binary intermetallic semiconductor compound belonging to the rare-earth pnictide family. This material is primarily of research and developmental interest, studied for potential applications in high-frequency electronics, photonic devices, and thermoelectric systems where rare-earth semiconductors offer unique electronic band structures. SmAs and related rare-earth arsenides are explored as alternatives to conventional III-V semiconductors in specialized applications requiring strong spin-orbit coupling or enhanced carrier mobility at extreme temperatures.
