· JVASP-28563· Te2Mo3Se2S2

Te2Mo3Se2S2 is a mixed chalcogenide compound combining tellurium, molybdenum, selenium, and sulfur—a research-stage material belonging to the family of layered transition metal dichalcogenides and polychalcogenides. This compound is primarily explored in materials science research for electronic and optoelectronic applications, leveraging the tunable band structure and layer-dependent properties characteristic of chalcogenide systems. The material's potential lies in next-generation semiconductor devices and energy conversion applications where conventional binary compounds (such as MoS2 or WTe2) show limitations, though it remains in the experimental phase without established high-volume industrial production.
