Large dynamic scissoring mode displacements coupled to band gap opening in Hybrid Perovskites

Autor: Bird, Tobias A., Chen, Jungshen, Songvilay, Manila, Stock, Chris, Wharmby, Michael T., Bristowe, Nicholas C., Senn, Mark S.

Hybrid perovskites are a rapidly growing research area, having reached photovoltaic power conversion efficiencies of over 25 \%. We apply a symmetry-motivated analysis method to analyse X-ray pair distribution function data of the cubic phases of the
