Fig. 1. Morphology of self-organized gold nanostructures on rippled templates. (a) Illustration of two-step fabrication routine. (b–f) Top-view SEM images for different gold thicknesses from 30 nm to 120 nm and (f) 30 nm with post-annealing at 400 °C. The insets show the corresponding 2D autocorrelations. (g) Cross-sectional bright-field TEM image of (f). Scale bars (b–f): 200 nm (insets 50 nm), (g) 50 nm.
