Rotor lattice model of ferroelectric large polarons

open access: yesPhysical Review Research, 2023
We present a minimal model of ferroelectric large polarons, which are suggested as one of the mechanisms responsible for the unique charge transport properties of hybrid perovskites. We demonstrate that short-ranged charge–rotor interactions lead to long-
