Figure 7

SEM images of Au tubes deposited on SiNWs with different diameters (a) 1 μm, (b) 450 nm, and (c) 45 nm. Insets in (a) and (b) show respective close cross-sectional views revealing the Au tube on Si nanowires. Arrow 1 in (c) indicates a broken tube structure. Arrow 2 in (c) indicates a Si nanowire template.
