· Cs2Hg5.75Cd0.25S7

Cs2Hg5.75Cd0.25S7 is a mixed-metal sulfide semiconductor compound combining cesium, mercury, cadmium, and sulfur in a layered crystal structure. This is primarily a research material rather than an established commercial compound, belonging to the family of ternary and quaternary metal chalcogenides being explored for optoelectronic and photonic applications. The substitution of cadmium into a mercury-based sulfide lattice creates tunable electronic properties, making it of interest to researchers investigating semiconductor band gaps, photocatalysis, and potential infrared or visible-light-responsive devices.
