· Sb4 Se4 I4

Sb₄Se₄I₄ is a mixed-halide chalcogenide semiconductor compound combining antimony, selenium, and iodine. This is an experimental material within the broader family of layered chalcogenide semiconductors, which are under active research for optoelectronic and photovoltaic applications due to their tunable bandgaps and strong light-matter interactions. The incorporation of iodine alongside selenium creates a mixed-anion system that can offer unique electronic properties distinct from binary antimony selenides, making it a candidate for next-generation thin-film photovoltaics, infrared detectors, and non-linear optical devices where bandgap engineering and anisotropic transport are advantageous.

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.
