When precession electron diffraction tomography goes dynamical

Résumé

The use of electron diffraction (ED) data for the refinement of crystal structures as routinely as what is done in X-ray diffraction (XRD) has long appeared to be inaccessible. While the strong electron/mater interaction allows studying crystals of nanometers size, the kinematic approximation is not valid, which makes the analysis of the diffracted intensity more complex than for XRD. More complex, but not impossible, as the formalism to describe dynamic conditions in ED is known since long. However, its use by programs aiming structural refinements using ED patterns obtained from parallel beam met no success despite several attempts.
