Figure 2

Topography and current images of sample A/B with height and current profiles of small QDs. Topography and current images of SL sample A (a, b) and BL sample B (d, e) with low dot densities. The height and current profiles of the marked small QDs of sample A and sample B are plotted in (c) and (f), respectively. It shows that the two marked QDs have similar sizes, but the current of the BL QD is about two times larger than that of the SL QD.
