Figure 5From: Large size self-assembled quantum rings: quantum size effect and modulation on the surface diffusionAFM image of QR and its morphology. (a) AFM image (10 × 10 μm2) of 15-ML QR grown on 14-ML In0.1 Ga0.9As layer. (b) the corresponding morphology of single QR, and (c) the cross-sectional profiles of QR in the [110] and[1–10] directions.Back to article page
