Figure 2

(a) Fourier-transformed k3χ data of Zn K-edge EXAFS measurements of ZnO-C:NW and ZnO-NW from k = 3.0 to 13.0 Å. Upper insets show angles θ between surface normal and direction of incident X-ray that are selected to obtain local atomic structure in surface and bulk regions. Lower insets display corresponding k3χ data of Zn K-edge EXAFS oscillations. (b) Two-dimensional atomic structure of ZnO-NW and (c) ZnO-C:NW.
