· JVASP-28858· Te3W2Se

Te3W2Se is a mixed-metal telluride compound combining tungsten with tellurium and selenium, belonging to the class of transition metal chalcogenides. This is a research-phase material rather than an established industrial alloy, investigated for its potential in thermoelectric and electronic applications where the layered chalcogenide structure offers tunable band gaps and carrier mobility. The combination of these elements positions it within material families explored for solid-state energy conversion and semiconductor device engineering.
