Low- and high-magnification TEM images and electron diffraction pattern of the ZnO-ZGO heterostructure. (a) Low-magnification TEM image of a single ZnO-ZGO heterostructure. (b) Electron diffraction pattern of the heterostructure. (c, d, e) High-resolution images of the heterostructure taken from various regions. The corresponding FFT images taken from the local lattice fringes are also shown in the insets.
