TeWSe
metal· JVASP-28417· TeWSe
TeWSe is a ternary metal compound composed of tellurium, tungsten, and selenium, belonging to the layered transition metal chalcogenide family. This material exists primarily in research and developmental contexts, where it is investigated for its potential in semiconductor applications, thermoelectric devices, and advanced electronic components due to the unique electronic properties characteristic of transition metal chalcogenides. TeWSe and related compounds are of particular interest for next-generation energy conversion and optoelectronic applications where layered crystal structures enable tunable band gaps and enhanced charge carrier mobility.
