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.…
Streaming Large-Scale Electron Microscopy Data to a Supercomputing Facility
Samuel S. Welborn, Chris Harris, Stephanie M. Ribet +4
Data management is a critical component of modern experimental workflows. As data generation rates increase, transferring data from acquisition servers to processing servers via co…
Relativistic ultrafast electron diffraction at high repetition rates
K. M. Siddiqui, D. B. Durham, F. Cropp +17
The ability to resolve the dynamics of matter on its native temporal and spatial scales constitutes a key challenge and convergent theme across chemistry, biology, and materials sc…
The 4D Camera: an 87 kHz direct electron detector for scanning/transmission electron microscopy
Peter Ercius, Ian J. Johnson, Philipp Pelz +19
We describe the development, operation, and application of the 4D Camera -- a 576 by 576 pixel active pixel sensor for scanning/transmission electron microscopy which operates at 8…
Probing Light Atoms at Sub-nanometer Resolution: Realization of Scanning Transmission Electron Microscope Holography
Fehmi S. Yasin, Tyler R. Harvey, Jordan J. Chess +4
Atomic resolution imaging in transmission electron microscopy (TEM) and scanning TEM (STEM) of light elements in electron-transparent materials has long been a challenge. Biomolecu…
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…
