Pushing the Boundary of the Stability and Band Gap Pareto Front by Going Towards High-Entropy Perovskites

Lead-free Cs 2 BX 6 (B = Zr 4+ , Sn 4+ , Te 4+ , Hf 4+ , Re 4+ , Os 4+ , Ir 4+ , Pt 4+ , and X = Cl – , Br – , I – ) vacancy-ordered double perovskites have gained significant attention due to their high performance...
