TaTlCu2S4
metal· JVASP-10574· TaTlCu2S4
TaTlCu₂S₄ is a ternary chalcogenide compound containing tantalum, thallium, copper, and sulfur. This is primarily a research material studied in solid-state chemistry and materials science for its potential electronic and thermoelectric properties, rather than an established commercial material. Compounds in this family are of interest for semiconductor applications, photovoltaic devices, and thermoelectric energy conversion due to their tunable band structures and mixed-metal coordination chemistry.
