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…

Improved Three-Dimensional Reconstructions in Electron Ptychography through Defocus Series Measurements
Marcel Schloz, Thomas C. Pekin, Hamish G. Brown +9
A detailed analysis of ptychography for 3D phase reconstructions of thick specimens is performed. We introduce multi-focus ptychography, which incorporates a 4D-STEM defocus series…
