The atomic structure of tetragonal MAPbI3. The atomic models of tetragonal MAPbI3 along a [100] and b [001] zone axis. The simulated electron diffraction (ED) patterns of tetragonal MAPbI3 along c [001], e [210], and g [10\(\bar 1\)] zone axes, respectively. d, h The selected area electron diffraction (SAED) and f fast Fourier transform (FFT) pattern of tetragonal MAPbI3. Note that there is a subtle difference between the experiment and simulation. The {110} diffraction spots appear to be dimmer in d, and the (00\(2\)) spot almost vanishes and the (006) spot disappears marked by yellow crosses in f, and the (020) spot is not observed marked by yellow crosses but additional {2h+1, 0, 2h+1} reflections [e.g., (101)] appear indicated by yellow circles in h.
