K8 Cu4 Br12
semiconductor· K8 Cu4 Br12
K8Cu4Br12 is a halide perovskite semiconductor compound containing potassium, copper, and bromine in a structured crystalline framework. This material belongs to the emerging class of hybrid and all-inorganic halide perovskites, primarily investigated in research for optoelectronic and photovoltaic applications due to its tunable bandgap and potential for solution-based processing. While not yet widely deployed in commercial products, copper-based halide perovskites are explored as alternatives to lead-containing variants, offering improved environmental sustainability and potential advantages in light emission, photon detection, and thin-film device fabrication.
