Au4 I4
semiconductor· 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.
