· InSb2S4Br

InSb₂S₄Br is a quaternary semiconductor compound combining indium, antimony, sulfur, and bromine elements, belonging to the family of mixed-halide chalcogenides. This is a research-phase material under investigation for optoelectronic and photovoltaic applications, where the combination of heavy metal elements and variable halide/chalcogenide ratios can be tuned to achieve specific bandgap and carrier transport properties. The material represents an emerging platform for exploring non-traditional absorber layers and quantum-confined structures, with potential advantages in thin-film solar cells, infrared detectors, and solid-state light sources where conventional semiconductors (Si, GaAs, CdTe) present cost or performance trade-offs.

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.
