CsCu3S2
metal· CsCu3S2
CsCu₃S₂ is a ternary chalcogenide compound combining cesium, copper, and sulfur—a semiconducting or semimetallic material belonging to the broader family of metal sulfides. This is a research-phase compound rather than an established engineering material, being investigated primarily for its potential thermoelectric and optoelectronic properties due to the electronic structure contributions from both the alkali metal (Cs) and transition metal (Cu) components.
