X-ray diffraction scattering and X-ray diffraction Microscopy of (80 nm) Pb(Zr0.2Ti0.8)O3/(50 nm) SrRuO3/SrTiO3 (001). a XRD scan along the (10) truncation rod of SrTiO3 (001), showing the PZT and SRO 103 Bragg peaks, Qz is the momentum transfer along the surface normal z, at an X-ray energy of 10 keV. b XDM images acquired at each Qz point in a. The total set of images is denoted by X(x,y,Q z ), where (x,y) corresponding to lateral sample positions and an effective pixel size of 15 nm. c A close-up view of an XDM image taken at the SRO 103 Bragg reflection, showing the presence of a network of misfit dislocations (dark lines) that relieve the strain imparted on SRO by the substrate, as well as other regions of the film that appear in dark contrast, indicating the presence of substantial in-plane lattice variations across the SRO layers. Scale bar is 1 µm and the color bar is normalized X-ray diffraction intensity
