Improving the low-dose performance of aberration correction in single sideband ptychography
Songge Li, Nicolas Gauquelin, Hoelen L. Lalandec Robert +5
The single sideband (SSB) framework of analytical electron ptychography can account for the presence of residual geometrical aberrations induced by the probe-forming lens. However,…

Hexatic Phase in Covalent Two-Dimensional Silver Iodide
Thuy An Bui, David Lamprecht, Jacob Madsen +10
According to the Kosterlitz-Thouless-Halperin-Nelson-Young (KTHNY) theory, the transition from a solid to liquid in two dimensions proceeds through an orientationally ordered liqui…

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…
