Figure 6
Simulated intensities of various Bragg peaks as a function of beam energy around the Br K edge for MAPbBrxI1−x compositions, comparing a randomly mixed model with layered arrangements of (a) diagonal layers, x = 0.5, and (b) vertical layers, x = 0.33. The insets visualize the respective layered models. Green spheres indicate iodide, pink spheres bromide, black spheres the organic cation and brown spheres lead. The numbers in the legend indicate the Miller indices of the respective diffraction peaks.
