Fig. 4

a STEM image of bipyramidal Au nanoparticles (AuNPs) with a width and length of ~20 nm and ~55 nm, respectively. The scale bar is 50 nm. b Measured CXD pattern from bipyramidal AuNPs binned by 11 × 11 pixels. c Profile along line P in b. d Reconstructed image of two bipyramidal AuNPs with a pixel size of 1 nm. The image is normalized to a 0–1 scale. The scale bar is 20 nm. e Phase-retrieval transfer function (PRTF) for the reconstructed image shown in d. The resolution was estimated to be 2.0 nm, based on the criterion of a PRTF threshold of 1/e.
