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,…
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…
Event driven 4D STEM acquisition with a Timepix3 detector: microsecond dwell time and faster scans for high precision and low dose applications
Daen Jannis, Christoph Hofer, Chuang Gao +4
Four dimensional scanning transmission electron microscopy (4D STEM) records the scattering of electrons in a material in great detail. The benefits offered by 4D STEM are substant…
