TeW2SeS2
metal· JVASP-28845· TeW2SeS2
TeW2SeS2 is a mixed transition metal chalcogenide compound combining tellurium, tungsten, selenium, and sulfur in a layered crystal structure. This material belongs to the family of two-dimensional transition metal dichalcogenides (TMDs) and related heterostructures, primarily investigated in research settings for next-generation electronic and optoelectronic devices. The compound's layered structure and tunable band gap make it a candidate for applications requiring thin-film semiconducting behavior, though it remains largely in the experimental phase and is not yet established in high-volume industrial production.
