Figure 2. (A) STM images depicting a characteristic Au(111) surface adorned with monoatomic steps. Images of 2D Pt layers formed after (B) 5 s and (C) 500 s of deposition at -0.8 V_SSCE. (D) High-contrast visual representation of the morphology of a 2D Pt layer on Au(111). (E) Linear defects within a Pt layer, arising from the elevation of the reconstructed Au substrate. Inset showcases a lower-magnification view. (F) A schematic depiction illustrating the Pt SED on Au(111). This figure is quoted with permission from Liu et al.^[44].
