Figure 7. Vertical alignment of ZnO nanowire arrays using textured seeds. (A) XRD and (B) plan view SEM data for an array grown from ZnO nanocrystal
seeds that were formed in situ on a silicon surface from the decomposition of zinc acetate at 350 °C. (C) Cross-sectional SEM image of an array showing
the absence of an intermediate nanoparticle layer.
