“…This is possible because data with angular diversity provide both 3D information and phase contrast. 2D phase of thin samples can be computed from images taken at multiple illumination angles [20][21][22][23][24] because of asymmetry introduced in the pupil plane [25]. All of these approaches assume a thin sample; in thick samples, angle-dependent data usually represent tomographic information.…”

“…Experimental exit wave function reconstructions using tilted illumination images have been performed successfully using a conventional TEM (Kirkland et al 1995(Kirkland et al , 1997, and have demonstrated an improvement in the limit of continuous information transfer from 0.2 nm to approximately 0.11 nm (Kirkland et al 1997). However, this represents a relatively modest improvement over the axial information limit for the instrument used (0.14 nm).…”

Transmission electron microscope (TEM) images recorded under tilted illumination conditions transfer higher spatial frequencies than axial images. This super resolution information transfer is highly directional in a single image, but can be extended in all directions through the use of complementary beam tilts during exit wave function reconstruction. We have determined the optimal experimental tilt magnitude for aperture synthesis in an aberration-corrected TEM. It is shown that electron-optical aberration correction allows the use of larger tilt angles and reduces the constraints that are imposed on experimental data acquisition in an uncorrected microscope. We demonstrate that, in many cases, the resolution improvement achievable is now limited by the sample and not by instrumental parameters. An exit wave function is presented that has been successfully reconstructed from a dataset of aberration-corrected images, including images acquired at a beam tilt of 18 mrad, which clearly demonstrates a resolution improvement from 0.11 nm to better than 0.08 nm at 200 kV.

The imaging and characterization of individual molecules and atomically thin, effectively one-dimensional crystals of rock salt and other halides encapsulated within single-walled carbon nanotubes are reviewed in this article. These species were imaged by conventional and super-resolved high-resolution transmission electron microscopy and by scanning tunneling microscopy, revealing the detailed atomic structure of these nanoscopic species.
