Using Aberrations to Improve Dose-Efficient Tilt-corrected 4D-STEM Imaging
Desheng Ma, David A Muller, Steven E Zeltmann
Tilt-corrected imaging methods in four-dimensional scanning transmission electron microscopy (4D-STEM) have recently emerged as a new class of direct ptychography methods that are…
