Abstract
- Typical electron dose rates that are used to capture single high resolution images induce atom (column) displacements that greatly exceed the average atom displacements  calculated from Debye-Waller factors at room temperature.
- The Born-Oppenheimer breaks down during the typical acquisition of high resolution images with beam current densities that greatly exceed 1000Â e/Ã 2s.
- A control of electron beam-sample interactions mandates reducing beam current densities down to single electrons/Ã 2s.
