Fig. 2

Self-assembled Au droplets synthesized via the variation of deposition amount (2–20 nm) on GaAs (111). The resulting Au droplets are shown with AFM top views in (ae). AFM images are 1 × 1 μm2. Cross-sectional line-profiles in (a-1)–(e-1) are acquired from the white lines in (ae). 2-D Fourier filter transform (FFT) power spectra are shown in (a-2)–(e-2). fi Average height, lateral diameter, density, and root-mean-squared (RMS) surface roughness. Error bars are ±5 %
