Au4 Br4
semiconductor· Au4 Br4
Au4Br4 is an experimental organometallic semiconductor compound consisting of gold and bromine in a 1:1 stoichiometric ratio. This material belongs to the family of metal halide semiconductors, which are of significant interest in emerging optoelectronic applications due to their tunable bandgap and potential for solution-based processing. While not yet commercialized, Au4Br4 represents the broader research effort to develop lead-free halide perovskites and related structures for next-generation photovoltaics, light-emitting devices, and photodetectors, offering potential advantages in stability and tunability compared to conventional inorganic semiconductors.
