a–e Time-series HRTEM images during the degradation of MAPbI3 under electron beam irradiation. The corresponding doses are marked on each panel. Scale bar, 4 nm. f–j The corresponding FFT patterns from MAPbI3 to 6H-PbI2. Circles indicate the superstructure diffraction reflections. Scale bar 2 nm−1.
