Te2 Mo1 W3 Se4 S2
semiconductor· Te2 Mo1 W3 Se4 S2
Te₂Mo₁W₃Se₄S₂ is a complex mixed-chalcogenide semiconductor compound combining tellurium, molybdenum, tungsten, selenium, and sulfur in a single phase material. This is an experimental research compound rather than a commercial material, belonging to the family of transition metal chalcogenides that exhibit tunable electronic and optoelectronic properties depending on composition. Such multielement chalcogenide semiconductors are investigated for their potential in next-generation photovoltaics, thermoelectrics, and photocatalysis, where the mixed composition can enable band gap engineering and improved charge carrier transport compared to binary or ternary alternatives.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
