Figure 8
Synchrotron X-ray diffraction contour colour plot of a selected 2θ region, collected using a ramp rate of 1 K and showing the temperature-dependent phase transition of FAPbBr₃ from Pnma to P4/mbm at 157 K (lower dashed black line) and from P4/mbm to $[Pm{\bar 3}m]$ at 264 K (upper dashed black line).
