TaCu3Se3S
metal· JVASP-104689· TaCu3Se3S
TaCu₃Se₃S is an experimental ternary compound combining tantalum, copper, selenium, and sulfur—a mixed chalcogenide system that bridges metallic and semiconducting character. This material remains primarily a research compound; its potential lies in thermoelectric and optoelectronic applications where copper-based chalcogenides and tantalum-containing phases have shown promise for solid-state energy conversion and photovoltaic studies.
