a The schematic set-up of iDPC-STEM. The electron beam was deflected by the potential field in specimens and detected by the four segments of DPC detector. b Four images detected by the four segments (A–D) of DPC detector, respectively. Scale bar, 20 nm. c The DPC image obtained from the four images in b. Scale bar, 20 nm. d The iDPC-STEM image obtained by a 2D integration of the DPC image in c. Scale bar, 10 nm. e The magnified iDPC-STEM image with the highest resolution, which is perfectly matched with the structural model. Scale bar, 5 nm. f The corresponding FFT pattern of e in a log scale, showing an information transfer up to 1.8 Å.
