We have used the One-Angstrom Microscope (OAM) to image and apply focal-series reconstruction (FSR) of the exit-surface wave (ESW) to a 70Angstrom particle of gold supported on amorphous carbon. The phase of the complex ESW shows the positions of the atom columns in the specimen as white dots, and its diffractogram shows it contains information to 1.23Angstrom. The result demonstrates that through-focal reconstruction of the ESW does not need large crystal expanses to work properly. Although [110] Au structures may not need sub-Angstrom resolution to show all the useful structural details of the particle in this orientation, it is clear that focal reconstruction of the ESW can improve original data that is much more difficult to interpret directly. We expect this technique to prove even more useful when applied to nanoparticles containing finer spacings than the 2.35Angstrom separation of the 111 planes in the present gold nano-particle.
