abstract = {Recent development in fast pixelated detector technology
has allowed a two dimensional diffraction pattern to be
recorded at every probe position of a two dimensional raster
scan in a scanning transmission electron microscope (STEM),
forming an information-rich four dimensional (4D) dataset.
Electron ptychography has been shown to enable efficient
coherent phase imaging of weakly scattering objects from a
4D dataset recorded using a focused electron probe, which is
optimised for simultaneous incoherent Z-contrast imaging and
spectroscopy in STEM. Therefore coherent phase contrast and
incoherent Z-contrast imaging modes can be efficiently
combined to provide a good sensitivity of both light and
heavy elements at atomic resolution. In this work, we
explore the application of electron ptychography for atomic
resolution imaging of strongly scattering crystalline
specimens, and present experiments on imaging crystalline
specimens including samples containing defects, under
dynamical channelling conditions using an aberration
corrected microscope. A ptychographic reconstruction method
called Wigner distribution deconvolution (WDD) was
implemented. Experimental results and simulation results
suggest that ptychography provides a readily interpretable
phase image and great sensitivity for imaging light elements
at atomic resolution in relatively thin crystalline
materials.},
