Figure 3: MIDI–STEM experiment of a heterogeneous sample.

(a) The image of the centre beam averaged from all diffraction patterns. Simultaneously, recorded images of gold NPs on a thin carbon support (b) using a virtual detector (edges outlined by red lines) shown in (a,c) using a conventional ADF-STEM detector. Scale bar, 2 nm. (d) Same as (b), with gold NPs shaded with random colours to emphasize the surrounding carbon. (e–g) Line traces with positions shown in (d) for images (b,c).
