Y1 Cu2 S2
semiconductor· Y1 Cu2 S2
Y1Cu2S2 is a ternary semiconductor compound combining yttrium, copper, and sulfur elements, belonging to the family of metal chalcogenides. This material is primarily of research interest rather than established industrial production, with potential applications in optoelectronic and thermoelectric devices where mixed-valence metal sulfides offer tunable electronic properties. The yttrium-copper-sulfide system is studied for photovoltaic absorbers, photodetectors, and solid-state energy conversion devices, positioning it as an emerging alternative to more conventional II-VI or I-III-VI2 semiconductors.
