· CuPS3

CuPS3 is a layered transition metal chalcogenide semiconductor composed of copper and phosphorus sulfide, belonging to the family of two-dimensional van der Waals materials with potential for electronic and optoelectronic applications. Currently primarily investigated in research settings, this material is being explored for its tunable band gap, anisotropic transport properties, and potential in next-generation thin-film devices; it represents a promising candidate in the broader push to develop alternative semiconductors beyond conventional silicon for flexible electronics, photodetectors, and low-dimensional device architectures.

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.
