· Au4 I4

Au4I4 is an experimental semiconductor compound composed of gold and iodine, belonging to the family of metal halide semiconductors being investigated for next-generation optoelectronic and photovoltaic applications. This material is primarily of research interest rather than established industrial production, with potential applications in perovskite-alternative solar cells, photodetectors, and light-emitting devices where halide semiconductors offer tunable bandgaps and solution-processing advantages over conventional silicon or III-V semiconductors.

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.
