Strain and SED maps in the growth plane of the upper QD. (a) ϵxx, (b) ϵyy, (c) ϵzz and (d) normalized SED calculated in the surface of the barrier layer. Superimposed to each map, we have included the APT data corresponding to the upper layer of QDs in the form of In concentration isolines, ranging from 25% In (dark blue) to 45% In (red), in steps of 5%. In (d), we have included an inset showing a complete map of the APT data for clarity.
