Ho2 S2 I2
semiconductor· Ho2 S2 I2
Ho₂S₂I₂ is a rare-earth halide sulfide compound combining holmium with sulfur and iodine, belonging to the family of mixed-anion semiconductors. This is primarily a research-phase material studied for its potential optoelectronic and photonic properties; it has not achieved widespread commercial adoption. The material's interest lies in exploring rare-earth semiconductor chemistry for next-generation photonic devices and as a platform for understanding how mixed anionic systems (sulfides + halides) can engineer bandgap and luminescence properties.
