Figure 2From: Morphological engineering of self-assembled nanostructures at nanoscale on faceted GaAs nanowires by droplet epitaxy SEM images. (a) QD, (b) hole in QD, (c) ‘square’ QR, (d) ‘rectangular’ QR, (e) 3D QR, (f) crescent QR, and (g) nano-antidots. Insets are magnified pictures of these nanostructures or 3D schematics.Back to article page
