· JVASP-28830· TeW2S3

TeW₂S₃ is a ternary chalcogenide compound combining tellurium, tungsten, and sulfur—a mixed-metal sulfide-telluride material primarily investigated in materials research rather than established industrial production. This compound belongs to the family of transition metal chalcogenides, which are of significant interest for semiconductor and energy storage applications due to their tunable electronic and optical properties. While not yet commercialized at scale, materials in this class show promise for photovoltaic devices, thermoelectric conversion, and catalytic applications where the layered structure and band gap engineering capabilities offer advantages over conventional alternatives.
