Dimensionality and Chirality in Halide Double Perovskites: A Coupled Design Framework for Polarization Control

Halide double perovskites have emerged as chemically versatile alternatives to lead halide perovskites, yet their functional behavior cannot be understood through simple structural analogy. In these materials, orbital decoupling at the band edges reconstructs electronic dispersion and defect energetics, establishing...
