Reconstruction of hk0.96 layers, shown with a consistent grayscale, for a superlattice composed of seven-unit-cell-thick PTO and seven-unit-cell-thick STO layers, repeated 12 times, with a ten-unit-cell-thick SRO buffer layer on an STO substrate. Data were collected at an SDD of 493.7 mm using 74 keV X-rays at varying incident angles. The reconstruction at an incident angle of 0.03° exhibits the most pronounced first-order diffuse ring with sufficient intensity. At smaller incident angles, the scattering intensity decreases due to the reduced beam cross section on the sample, while at higher angles the surface sensitivity is compromised.
