SEM images of ZnO NRs grown with different durations and AFM surface image of AZO film. (a to e) Top-view and (f,g) cross-sectional SEM images of ZnO NRs grown with different durations: (a) S1 - 3 min, (b,f) S2 - 6 min, (c) S3 - 8 min, (d) S4 - 9 min, and (e,g) S5 - 12 min; insets are the high-magnification images of the corresponding samples. (h) AFM surface image of AZO film.
