Figure 10. Surface damage revealed by multislice ptychography in experiment^[94]. The top, central and bottom slices are displayed in (A-C), respectively. The depth values are labeled on the bottom left of each image. The sample is an 18-nm-thick TiZrNb medium-entropy alloy doped with oxygen. The object is separated into 1.2-nm-thick slices during the reconstruction. Surface damage can be seen from the top and bottom slices.
