Cd2 Bi2 S4 Br2
semiconductor· Cd2 Bi2 S4 Br2
Cd₂Bi₂S₄Br₂ is a mixed-halide cadmium bismuth chalcogenide semiconductor belonging to the family of layered ternary and quaternary semiconducting compounds. This is primarily a research material of interest for optoelectronic and photovoltaic applications, where the combination of cadmium, bismuth, sulfur, and bromine creates tunable bandgap and electronic properties distinct from simpler binary semiconductors. The material represents an emerging class of environmentally motivated alternatives to lead-based perovskites and conventional III–V semiconductors, though it remains largely in the experimental phase with potential applications in thin-film photovoltaics, photodetectors, and light-emitting devices.

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.
