metal· JVASP-28504· Te4Mo2WSe2
Te4Mo2WSe2 is an experimental transition metal chalcogenide compound combining tellurium, molybdenum, tungsten, and selenium in a mixed-metal configuration. This material family is primarily investigated in research contexts for potential applications in thermoelectric devices, optoelectronic systems, and energy conversion, where the layered chalcogenide structure can offer tunable electronic and phononic properties. The multi-element composition allows researchers to engineer band gaps and phonon scattering mechanisms, making it a candidate for next-generation solid-state cooling or power generation where conventional materials face efficiency limits.
