Mo3 W1 Se2 S6

Mo₃W₁Se₂S₆ is a mixed transition metal chalcogenide semiconductor belonging to the layered dichalcogenide family, combining molybdenum, tungsten, selenium, and sulfur in a defined stoichiometry. This is primarily a research material investigated for its electronic and optoelectronic properties, offering tunable band gaps and enhanced carrier mobility compared to single-component dichalcogenides (MoS₂ or WS₂ alone). The alloying of Mo and W with mixed chalcogens (Se/S) is of interest in emerging applications requiring heterostructured two-dimensional materials with improved light absorption, charge transport, and catalytic activity.
