Figure 3
HRTEM images of NRs. (a) HRTEM images showing the crystallographic orientation of the nanowire with saw-like edges in the course of the conversion to the NRs. The inset at the top shows interface between the basal nanowire and saw-like edge. The inset at the bottom shows the basal nanowire. The scale bar in the images is 5 nm. Corresponding SAED pattern recorded along the [-111] zone axis (b) and EDS spectrum (c).
