Figure 4.

Quantitative analysis of the effect of the pre-growth annealing on the size/diameter of the nanoparticles/nanowires. (a) The plot of the size of the nanoparticles versus the thickness of Au films, after annealing at 600°C. (b) The plot of the size of the nanoparticles versus the thickness of Au films, after annealing at 650°C. (c) The plot of the diameter of the GaAs nanowires versus the thickness of Au films. (d) The plot of the length and density of the GaAs nanowires versus the thickness of Au films.
