Dynamic shortening of disorder potentials in anharmonic halide perovskites
Halide perovskites have sharp optical absorption edges, which seems contradictory to the amount of disorder in the materials. Here Gehrmann and Egger show that the disorder potential is short-range correlated and can thus reconcile with the sharp optical absorption edges and small Urbach energies.
