Figure 9.

P_surf as the function of the rescaled local roughness (ρ(l) − ρ_min(l))/(ρ_max(l) − ρ_min(l)) of the growing layer, for different sizes L = 160, 320, 640, 1280 μm (as in figure 7), s = 0.02, and l = 10 μm (red), l = 35 μm (green), l = 98 μm (blue). Data points for different L and l collapse onto a single curve. The corresponding ρ_max(l) (the largest of the simulated ρ(l) for a given l) are 1.3, 3.1, 6.4 μm and ρ_min(l) (the smallest ρ(l) for a given l) are 0.7, 1, 1.3 μm. (Online version in colour.)
