Figure 1

SEM images of evolved nanostructures grown at the growth temperature of 1,000°C. (a) Overall top-view SEM image of the sample where the gas flow direction is indicated by the double arrows. Insert is the EDX analysis of the nanostructures. (b) SEM image of a single post from the upper part indicated in (a). (c) SEM image of a single post from the middle part indicated in (a). (d) SEM image of a single post from the bottom part indicated in (a). (e, f, g) Enlarged SEM images of (b), (c), and (d), respectively.
