· JVASP-28962· TeMoWSe2S

TeMoWSe₂S is a mixed transition-metal dichalcogenide compound combining molybdenum, tungsten, tellurium, selenium, and sulfur in a layered crystal structure. This is primarily a research material being investigated for its tunable electronic and optoelectronic properties, as compositional variation in this family enables bandgap engineering and modification of mechanical behavior without requiring separate material selection. While not yet in widespread industrial production, dichalcogenides of this type show promise in next-generation electronics and catalysis where the combination of transition metals and mixed chalcogens creates synergistic effects unavailable in binary compounds.

Export Control

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.
