· Te4 Mo1 W2 Se2

Te₄Mo₁W₂Se₂ is a mixed-chalcogenide semiconductor compound combining tellurium, selenium, molybdenum, and tungsten in a complex stoichiometry. This is an experimental material primarily explored in research contexts for its potential as a narrow-bandgap or mid-infrared semiconductor, belonging to the family of transition-metal chalcogenides that exhibit layered crystal structures and anisotropic electronic properties. The material's multi-element composition offers tunable optical and electronic characteristics compared to binary or ternary chalcogenides, making it of interest for advanced optoelectronic and sensing applications where bandgap engineering is critical.
