(a) A schematic diagram of the sample environment for in situ ptychography with a limited tilting angle, including the MEMS chip sample holder (Fam et al., 2019). (b) A SEM image acquired during FIB–SEM showing a CoMn2O4 spinel `hollow-sphere' particle of approximately 3 µm diameter attached to the viewing window of the MEMS chip. |
