Figure 1

TEM images of ZnO nanorods and nanotubes. (a) LRTEM image of partially etched ZnO nanorod (white arrow). Non-etched part of the ZnO nanorod contains a lot of bubbles in its core (red dotted circle). The insert shows SAED pattern indicating the growth orientation along [0001]. (b, c) HRTEM images from different spots (red squares). (d, e) Comparative analysis of surface defects distribution on the walls of same nanotube from bright and dark field images.
