· Te2 Mo4 Se2 S4

Te₂Mo₄Se₂S₄ is a mixed-chalcogenide semiconductor compound combining tellurium, molybdenum, selenium, and sulfur in a layered crystal structure. This is an experimental research material belonging to the family of transition metal dichalcogenides and their mixed-composition variants, investigated for optoelectronic and photovoltaic applications where bandgap tuning and heterostructure engineering are critical. The quaternary composition enables precise control of electronic and optical properties compared to binary or ternary chalcogenides, making it of interest for next-generation thin-film photovoltaics, photodetectors, and potentially thermoelectric devices where composition-dependent performance offers design flexibility.

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.
