Ca(GdS2)2
semiconductor· Ca(GdS2)2
Ca(GdS₂)₂ is a ternary chalcogenide semiconductor compound composed of calcium, gadolinium, and sulfur, belonging to the broader family of rare-earth sulfide materials. This is a research-phase compound studied primarily for its potential in photonic and optoelectronic applications, where rare-earth sulfides are explored for their tunable bandgaps and luminescent properties. The material remains largely experimental; adoption in engineering would depend on demonstrating cost-effective synthesis, thermal stability, and reproducible performance relative to established alternatives like rare-earth oxides or conventional semiconductors.
