· Mo1 W1 Se4

Mo₁W₁Se₄ is a mixed-metal diselenide semiconductor compound belonging to the transition metal chalcogenide family, combining molybdenum and tungsten with selenium. This material is primarily of research interest for next-generation electronic and optoelectronic devices, where layered transition metal dichalcogenides are explored as alternatives to traditional semiconductors for applications requiring reduced dimensionality, tunable bandgap, and enhanced light-matter interactions. The tungsten-molybdenum combination offers potential advantages in band engineering and carrier mobility compared to single-metal diselenides, making it relevant for emerging technologies in flexible electronics and energy conversion.
