The evolution of self-assembled Au droplets on GaAs (111)B. The results are shown with the (a-h) AFM top-view images of 1 × 1 μm2 and the corresponding cross-sectional line profiles in (a-1) to (h-1) with the FFT power spectra in (a-2) to (h-2). The AFM top-view images of 3 × 3 μm2 are presented in (e-3) to (h-3), and the AFM side-view images of 1 × 1 μm2 are shown in (e-4) to (h-4) along with the corresponding height distribution histograms in (e-5) to (h-5).
