· JVASP-92389· TlCo2S2

TlCo₂S₂ is an intermetallic compound combining thallium with cobalt sulfide, belonging to the family of ternary metal chalcogenides. This is a research-phase material not yet established in mainstream engineering production; it represents the broader class of cobalt-based sulfides and thallium compounds being investigated for their electronic and magnetic properties. Interest in such ternary compounds stems from potential applications in thermoelectric devices, magnetic materials, and semiconductor systems where the combination of heavy thallium atoms with transition metal-sulfide frameworks can produce favorable band structures and transport properties.
