K4 In4 Br12
semiconductor· K4 In4 Br12
K4In4Br12 is an inorganic halide perovskite compound composed of potassium, indium, and bromine, belonging to the family of lead-free metal halide semiconductors. This material is primarily of research interest for optoelectronic applications, where it is being investigated as a potential replacement for lead-based perovskites in photovoltaic and light-emission devices. Its appeal lies in improved environmental and toxicity profiles compared to lead halide perovskites, though it remains largely in the experimental stage with ongoing work to optimize its electronic properties and stability for practical device integration.
