Er3 As1
semiconductor· Er3 As1
Er₃As₁ is a binary intermetallic compound composed of erbium and arsenic, belonging to the rare-earth arsenide family of semiconductors. This material is primarily of research interest for potential applications in thermoelectric devices and infrared optoelectronics, where rare-earth arsenides are explored for their narrow bandgap and carrier transport properties. While not yet widely deployed in mainstream engineering, Er₃As₁ represents a candidate material in the broader class of rare-earth pnictides being investigated for advanced solid-state energy conversion and quantum device applications.
