abstract = {We investigate a possible dependence between the applied
electron dose-rate and the magnitude of the resulting image
contrast in HRTEM of inorganic crystalline objects. The
present study is focussed on the question whether electron
irradiation can induce excessively strong atom vibrations or
displacements, which in turn could significantly reduce the
resulting image contrast. For this purpose, high-resolution
images of MgO, Ge, and Au samples were acquired with varying
dose rates using a CS-corrected FEI Titan 80–300
microscope operated at 300 kV accelerating voltage. This
investigation shows that the magnitude of the signal
contrast is independent from the dose rates occurring in
conventional HRTEM experiments and that excessively strong
vibrations or displacements of bulk atoms are not induced by
the applied electron irradiation.},
