• not only nanorods but also fill in the gaps between them (Figure 4). Samples A and B show a core-shell structure with the zinc oxide nanorod being the core and the AZO layer being the shell. For closely packed nanorods (sample C) the AZO film is grown only on the top of the nanorods. However, we also
