· Mo2 W2 Se2 S6

Mo₂W₂Se₂S₆ is a mixed-metal dichalcogenide semiconductor composed of molybdenum, tungsten, selenium, and sulfur in a layered structure. This is an experimental material in the 2D/transition-metal dichalcogenide (TMD) family, synthesized primarily for research into optoelectronic and energy-conversion applications where tunable bandgap and strong light-matter interaction are advantageous. The alloying of two metals (Mo and W) with two chalcogens (Se and S) allows researchers to engineer electronic properties beyond what single-phase materials like MoS₂ or WS₂ offer, making it relevant for emerging technologies in photovoltaics, photodetectors, and catalysis, though production and integration pathways remain under development.

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.
