· Cs2Cd1.35Hg4.65S7

Cs2Cd1.35Hg4.65S7 is a mixed-metal sulfide semiconductor compound combining cesium, cadmium, and mercury in a layered crystal structure. This is a research-phase material from the family of ternary and quaternary sulfide semiconductors, synthesized primarily for fundamental studies of electronic band structure and potential optoelectronic applications rather than established commercial use. Interest in this compound centers on tuning bandgap and carrier transport through metal composition variation—a strategy relevant to photovoltaics, radiation detection, and infrared sensing, though practical deployment remains limited pending demonstration of reproducibility, stability, and scalability.
