Evolutionary exploration of polytypism in lead halide perovskites
Zhenzhu Li, Ji‐Sang Park, Aron Walsh
Abstract
polytypes are analysed to identify features of polytypism such as the distinct arrangements of layers and symmetry forbidden sequences. A number of polytypes with low ordering energies (around thermal energy at room temperature) are predicted, which could form distinct phases or appear as stacking faults within perovskite grains.
