Figure 2
(a) Full detector frame (384 × 384 pixels) recorded for position 9 along the nanowire growth axis, demonstrated in Fig. 1. Spatially separated from the Si Laue reflections which are indexed in red, four neighboring Au reflections (553, 755, 444 and 555) are visible. (b)–(d) Energy spectra extracted for the four Au and Si 12 0 0 and 14 0 reflections are plotted in the range of 14 to 24 keV. Blue, black and red line profiles represent the energies of the background, Au and Si, respectively. The positions at which the background was extracted are indicated by light-blue crosses in (a). |
