· Te2 Mo1 W3 Se2 S4

Te₂Mo₁W₃Se₂S₄ is a mixed-chalcogenide semiconductor compound combining tellurium, molybdenum, tungsten, selenium, and sulfur in a layered structure. This is a research-phase material belonging to the transition metal chalcogenide family, designed to explore tunable electronic and optoelectronic properties through compositional engineering of multiple chalcogen and metal sites. The material's potential lies in next-generation thin-film photovoltaics, thermoelectric devices, and 2D electronic applications where the deliberate mixing of heavy (Te) and lighter (S, Se) chalcogens alongside multiple transition metals (Mo, W) offers flexibility in band-gap tuning and charge-carrier mobility that single-component or binary semiconductors cannot easily match.

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.
