4D-STEM: 4D-STEM microscopy was performed using a Thermo Fisher Spectra 300 microscope operated at 200 kV. Diffraction patterns were acquired using a Medipix3 direct electron detector. A 0.1 mrad convergence angle was used and the camera length set such that a resolution of 0.7 Å could be measured. The beam current was 2 pA with a 1 ms dwell time, leading to a cumulative dose per scan of ~ 10 electrons / Å 2 . Analysis of 4D-STEM data was carried out using hyperspy and pyxem libraries.
