· Te2 Mo2 W1 Se2 S2

Te₂Mo₂W₁Se₂S₂ is an experimental mixed-chalcogenide semiconductor compound combining tellurium, molybdenum, tungsten, selenium, and sulfur—a complex composition designed to engineer bandgap and electronic properties beyond single-element or binary semiconductors. This material belongs to the family of transitional metal dichalcogenides (TMDs) and high-entropy semiconductors, which are primarily investigated in research settings for optoelectronic and photovoltaic applications where tunable electronic structure and reduced defect sensitivity are advantageous over conventional semiconductors.

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.
