(a) Sketch of the experimental setup. The focused X-ray beam illuminates part of the NW and produces a diffraction signal, as illustrated by the examples of detector images shown as insets. Typical detector images include diffraction signal of the illuminated NW and the substrate's crystal truncation rod (CTR). (b) Diffraction geometry with respect to the NW cross section at the sample azimuth ϕ = 0° in comparison with a top view SEM image. |
