Figure 3From: Structure-dependent growth control in nanowire synthesis via on-film formation of nanowires SEM images of Bi nanowires grown on Bi films with different areas: (a) (104 μm)2, (b) (103 μm)2, (c) (102 μm)2, and (d) (10 μm)2. Insets show optical microscope images of the samples before annealing. (e) Histograms of Bi nanowire densities depending on the Bi film areas.Back to article page
