Figure 2
Scanning X-ray diffraction images of nw1 and nw2 and their surrounding for various Bragg peaks are shown. Images created by the GaAs ZB [(\bar{3}\bar{3}\bar{1})], WZ [(01\bar{1}\bar{5})] and twinned ZB [(\bar{2}\bar{2}\bar{4})] Bragg peaks are shown in panels (a, d), (b, e) and (c, f), respectively. The colour scale is adjusted to yield an appropriate contrast within the image. Especially at the [(\bar{3}\bar{3}\bar{1})] peak the constant contribution of the substrate is ignored. The NW appears as an elongated object since the incidence angles at the Bragg conditions are between 59 and 62°.
