Figure 8
Multimodal images measured within the red rectangle indicated in the As distribution in Fig. 7. The dark field (b) and reconstructed phase (d) of the sample area within the green rectangle shown in the As distribution map (a) reveal complex sample morphology. (c) Coherent diffraction pattern in the sample spot marked by the orange arrow. The approximate highest (130 nm) resolution As distribution maps (e) correspond to the red rectangles in (a). (f) XANES spectra measured around the As K-edge; red curve: at the indicated sample point; green curve: As2O5 standard. The XANES spectra of the sample and the As2O5 standard were shifted laterally for the clarity of the figure. |
