Multi-angle precession electron diffraction (MAPED): a versatile approach to 4D-STEM precession

Stephanie M. Ribet, Rohan Dhall, Colin Ophus +1

Precession of a converged beam during acquisition of a 4D-STEM dataset improves strain, orientation, and phase mapping accuracy by averaging over continuous angles of illumination.…

Interpretable and efficient contrast in scanning transmission electron microscopy with a diffraction grating beamsplitter

Tyler R. Harvey, Fehmi S. Yasin, Jordan J. Chess +9

Efficient imaging of biomolecules, 2D materials and electromagnetic fields depends on retrieval of the phase of transmitted electrons. We demonstrate a method to measure phase in a…
