Figure 4
Comparison of maximum intensity versus mean intensity. (a) Maximum pixel intensity image and (b) normalized summed (mean) intensity image across a 26° rotation for an Au(111) electrode in 0.1 M NaOH at 0.1 V (versus RHE). Both images are plotted on the same color scale. The semi-circles are powder rings, and the dark circles are where beam stops have been placed to protect the detector from high-intensity Bragg reflections from the bulk Au(111) single crystal. Running through the masked Bragg reflections are the CTRs; these arise from the termination of the Au(111) crystal. To the side are super-structure rods from the surface reconstruction (closest rods to the edge of the detector). These arise only from the top layer of atoms which have a different periodicity.
