K2 Br10 Sn4
semiconductor· K2 Br10 Sn4
K2Br10Sn4 is a halide perovskite-related semiconductor compound combining potassium, bromine, and tin in a layered or framework structure. This material belongs to the emerging family of tin-based halide semiconductors, which are being investigated as lead-free alternatives for optoelectronic applications due to their tunable bandgap and solution-processable synthesis. The compound represents exploratory materials chemistry aimed at improving stability and reducing toxicity concerns associated with lead halide perovskites used in photovoltaics and light-emission devices.
