Fig. 8.8 Morphological and structural characteristics of typical ZnO NT bundles obtained by
hydrothermal method: (A, B, and C) low-magnification and high-magnification images of the
FE-SEM images of ZnO NT bundles; (D) TEM image. The upper-left and lower-right inset
images of (D) are the SAED pattern and the HRTEM image of a single NT, respectively.
