Fig. 4. (a)Representative TEM image of ZnO tetrapods. Upper inset is lowmagnified image and lower inset shows electron diffraction pattern showing high crystallinity. (b) High resolution TEM image of square area in (a) reveals interplanar distance along the c-axis of ZnO tetrapod. Inset is a corresponding FFT pattern.
