· JVASP-139771· CuTeSBr

CuTeSBr is a copper-based chalcogenide compound containing tellurium, sulfur, and bromine elements. This is a quaternary semiconductor material primarily of research interest rather than established industrial production, with potential applications in photovoltaic devices and thermoelectric systems where mixed halide-chalcogenide compositions can offer tunable electronic properties. The material represents an exploratory class within copper chalcogenide semiconductors, positioned for investigation in next-generation energy conversion technologies where compositional flexibility enables optimization of bandgap and carrier transport.

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.
