· Te4 Mo2 W2 Se2 S2

Te4Mo2W2Se2S2 is a complex chalcogenide semiconductor compound combining tellurium, molybdenum, tungsten, and mixed selenium-sulfur anions in a single phase. This is a research-stage material being investigated for its unique electronic and optical properties arising from the layered transition metal dichalcogenide family, which exhibits tunable band gaps and strong light-matter coupling. Potential applications span optoelectronic devices, energy harvesting, and next-generation photovoltaics where the multi-element composition may enable bandgap engineering and improved charge carrier dynamics compared to binary or ternary dichalcogenides.
