Figure 4
Visualization of internal voids in colloidal gold particles at 8 keV. (a) SEM image of the sample. (b) Diffraction pattern of the sample. (c) Projected electron density map reconstructed from the pattern in (b), where one pixel corresponds to 7.3 nm. (d) Phase retrieval transfer function of the map. The thin line indicates the spatial frequency corresponding to the effective resolution. The scale bars in (a) and (c) indicate 300 nm. The colour scales are shown at the top (b) and left (c) of each panel. |
