Figure 8

SEM images and schematic of structure of heterostructure NWs and distribution of diameters. (a) SEM images of grown NWs and schematic of cross-sectional structure of NW containing GaAs QW. GaAs cap layer is not shown in schematic. Inset SEM image in upper right is top view of NW. (b) Histogram of diameter distribution for NWs with pitch of 𝑎 = 0 . 5 μm [30].
