Ba1 Sr1 I4
semiconductor· Ba1 Sr1 I4
Ba₁Sr₁I₄ is a halide perovskite semiconductor compound combining barium, strontium, and iodine in a layered crystal structure. This material is primarily investigated in research contexts for next-generation optoelectronic and photovoltaic applications, where the mixed-cation composition offers potential for tuned bandgap and improved stability compared to single-cation iodide perovskites. Engineers consider halide perovskites like this compound for applications requiring low-cost solution processing, high light absorption, and tunable electronic properties, though commercialization remains limited due to ongoing challenges with long-term stability and lead-free alternatives.
