FIG. 3.(left) Scanning transmission electron microscopyimage of an APB within a 3C-SiC (001) substrate. (right) Zoom of the surface depletion induced by the APB and lying at the (001) surface. It is worth noting that during the experimental growth along the [001] direction, the APB moves along the [110] direction, reaching a final tilted configuration with respect to the (001) surface. The KMC evolution reported in Fig. 2 agrees quite well with the experimental analysis of this figure.
