(a,b) Snapshots [from Fig. 1(a)] of the growth of a 3D island (black intensity) before (a) and after (b) it crosses the delimiting step with the terrace marked by the red arrow. Between (a) and (b), the adatom concentration of the terrace marked by the red arrow has decreased toward its stationary value (\({c}_{{\rm{stat}}}\simeq 0.04\,{\rm{ML}}\)). The scale bar is 1.5 μm and ε = 24 eV. (c) Intensity time-evolution of the atomic terraces indicated in (a) by red and black arrows. The timeline of the snapshots (a) and (b) is displayed.
