Figure 2
Three examples of diffraction patterns at different scan positions from the sample shown in Fig. 1(a) are presented on a logarithmic scale. (a) Empty background (blue). (b) On the boundary (red). (c) Within the sample (green). The inset in each diffraction pattern shows the central direct beam on a linear scale. The edge feature [marked by a dashed white line shown in (b)] is visible when the beam was on the boundary of the particle. |
