Figure 5.

Temperature dependence of the annealing behaviour for (a) the height of the clusters, (b) the percentage of surface covered by the clusters, and (c) the number of clusters per area (cluster density n). The annealing process can be divided into two parts: First, for mild annealing (T ≤ 500 K) where no diffusion takes place (indicated by the red dashed line), and second, for higher annealing temperatures with an exponential increase in height, and an exponential decay in coverage and number of clusters per area (solid red line).
