High-resolution x-ray scanning with a diffuse, Huffman-patterned probe to minimise radiation damage

Alaleh Aminzadeh, Andrew M. Kingston, Lindon Roberts +3

Scanning objects with a more tightly focused beam (for example of photons or electrons) can provide higher-resolution images. However the stronger localisation of energy deposition…

Differential phase contrast from electrons that cause inner shell ionization

Michael Deimetry, Timothy C. Petersen, Hamish G. Brown +2

Differential Phase Contrast (DPC) imaging, in which deviations in the bright field beam are in proportion to the electric field, has been extensively studied in the context of pure…

Clustering of negative topological charge precedes plastic failure in 3D glasses

Arabinda Bera, Matteo Baggioli, Timothy C. Petersen +2

The deformation mechanism in amorphous solids subjected to external shear remains poorly understood because of the absence of well-defined topological defects mediating the plastic…

Suppressing dynamical diffraction artefacts in differential phase contrast scanning transmission electron microscopy of long-range electromagnetic fields via precession

T. Mawson, A. Nakamura, T. C. Petersen +5

In differential phase contrast scanning transmission electron microscopy (DPC-STEM), variability in dynamical diffraction resulting from changes in sample thickness and local cryst…
