Pushing the Dose Limit of Atomic-Resolution Imaging: A 4D-STEM case study of NaCl
Tamazouzt Chennit, Arno Annys, Songge Li +3
Beam-induced damage fundamentally limits the characterization of beam-sensitive materials by scanning transmission electron microscopy (STEM), since structural information must be…
Designing dislocation-driven polar vortex networks in twisted perovskites
William Sandholt, Nicolas Gauquelin, John Mangeri +21
Twisting two atomic layers produces a geometric moire pattern, but bonding-induced interfacial reconstruction fundamentally transforms this into an ordered dislocation network - a…
Guided progressive reconstructive imaging: a new quantization-based framework for low-dose, high-throughput and real-time analytical ptychography
Hoelen L. Lalandec Robert, Arno Annys, Tamazouzt Chennit +1
By profiting from recent developments in detector technologies, making it possible to access a stream of detection events with few-ns time resolutions, a new ptychographic workflow…
Investigating the convergence properties of iterative ptychography for atomic-resolution low-dose imaging
Tamazouzt Chennit, Songge Li, Hoelen L. Lalandec Robert +6
This study investigates the convergence properties of a collection of iterative electron ptychography methods, under low electron doses ( 10 ) and gives particular…
Phase offset method of ptychographic contrast reversal correction
Christoph Hofer, Chuang Gao, Tamazouzt Chennit +2
The contrast transfer function of direct ptychography methods such as the single side band (SSB) method are single signed, yet these methods still sometimes exhibit contrast revers…
