Resumen: Herein, we show how electron microscopy can provide atomic-level understanding of FAPbBr3 , where electron diffraction and high-resolution imaging were combined allowing not only the characterization of the pristine material but also the identification of different intermediates upon its structural disintegration. Additionally, a minor tetragonal phase was also identified whose structure was also solved.
