(Left) Topology of the various silver surfaces by AFM or scanning electron microscopy. (A and B) The silver films of 100 and 5 nm thick made by thermal evaporation. (C) Compacted nanoparticle films. (D) Nanorod arrays. (E) Cluster–cluster aggregated films. (F) Mirror reaction films. The size of each image is 2 μm × 2 μm. The height scales are shown in the images. (Right) Self-similarity analysis for the different silver surfaces shown in A: 100-nm-thick evaporated silver films (▪); 5.2-nm-thick evaporated silver films (○); compacted nanoparticle films (•); cluster–cluster aggregated films (▴); and mirror reaction films (▿).
