Sn4 I4 Cl4
semiconductor· Sn4 I4 Cl4
Sn₄I₄Cl₄ is a mixed-halide tin compound belonging to the family of halide perovskites and perovskite-related semiconductors. This is primarily a research material rather than an established engineering material, investigated for its semiconducting and optoelectronic properties as part of broader efforts to develop lead-free alternatives to conventional halide perovskites. The material's potential lies in photovoltaic devices, light-emitting applications, and radiation detection, where the combination of tin, iodide, and chloride provides tunable bandgap and electronic properties while avoiding the toxicity concerns of lead-based compounds.
