Figure 5
Ptychography images from thermal annealing of np-Au under a He environment. Overview scans: (a) before and (b) after thermal annealing. Highlighted area in (a) and (b) shown: (c) at 293 K, (d) 923 K after 0 min, (e) 923 K after 15 min and (f) 923 K after 30 min. Darker intensity in phase maps indicates areas rich in Au, while brighter voids indicate annealing and absence of Au ligaments. Pt glue from FIB is visible as intense features in the corners of (a) and (b). |
