· Cs2Hg4.65Cd1.35S7

Cs2Hg4.65Cd1.35S7 is a mixed-metal sulfide semiconductor compound containing cesium, mercury, cadmium, and sulfur in a layered crystal structure. This is a research-phase material within the ternary and quaternary metal sulfide family, studied primarily for its semiconducting properties and potential in photonic and optoelectronic applications. While not yet in widespread industrial production, materials in this chemical family are investigated as alternatives to more toxic or less efficient semiconductors, with potential relevance to photovoltaics, nonlinear optics, and radiation detection where the band gap and crystal structure can be engineered through metal substitution.
