· Te2 Mo1 W2 S4

Te₂Mo₁W₂S₄ is a mixed-metal dichalcogenide semiconductor composed of tellurium, molybdenum, tungsten, and sulfur. This is a research-phase layered compound belonging to the transition metal chalcogenide family, which has attracted interest for its tunable electronic and optoelectronic properties arising from its ternary metal composition. The material represents an emerging class of semiconductors being explored for next-generation devices where bandgap engineering and heteroatom substitution offer advantages over binary TMDs (like MoS₂ or WS₂) in controlling charge carrier behavior and light absorption.

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.
