Figure 1.

Cross-sectional and top-view SEM images of the samples. Cross-sectional SEM images of the electrochemically synthesized (a) ZnO nanorods on ITO/glass without the seed layer, (b) ZnO NRAs/zinc acetate seed layer on ITO/glass, (c) ZnO NRAs/MWCNT (2 wt.%)-composed seed layer on ITO/glass, and (d) ZnO NRAs/MWCNT (5 wt.%)-composed seed layer on ITO/glass. The insets show the top-view SEM images of the corresponding samples.
