Ho2 S1 O2
semiconductor· Ho2 S1 O2
Holmium oxide sulfide (Ho₂S₁O₂) is a rare-earth compound semiconductor combining holmium with sulfur and oxygen, representing a mixed-anion material in the lanthanide family. This is primarily a research-phase compound with potential applications in optoelectronics and photonic devices, where rare-earth semiconductors are explored for their unique optical and electronic properties. The material's significance lies in its potential for mid-infrared light emission and high-refractive-index applications, though industrial adoption remains limited compared to established rare-earth oxides or III-V semiconductors.
