Sb4 S4 I4
semiconductor· Sb4 S4 I4
Sb₄S₄I₄ is a quaternary semiconductor compound combining antimony, sulfur, and iodine—a mixed-halide chalcogenide material that bridges traditional IV-VI semiconductors and halide perovskite families. This is primarily a research-phase material being explored for optoelectronic and photovoltaic applications where tunable bandgap, high absorption coefficients, and layered crystal structures offer advantages over conventional semiconductors; industrial adoption remains limited, but the material class shows promise for thin-film solar cells, infrared detectors, and nonlinear optical devices due to the combined effects of heavy-metal d-orbitals and halide chemistry.

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.
