Figure 3
AFM images of PS-b-PMMA thin films with a thickness of 56 nm for different SVA times. (a) 0 h, (b) 0.5 h, (c) 1.0 h, (d) 2.0 h, (e) 3.5 h, (f) 5.5 h, (g) 18.0 h, and (h) 31.0 h. The height bar is adapted individually as indicated. The green hexagons indicate that the positions of these half-spheres are not well located at the apex of the hexagon. The red hexagons indicate that the positions of these half-spheres are well located at the apex of the hexagon. On the top right corners in (d–g), the insets show the corresponding 2D fast Fourier transform (FFT) patterns.
