=================================================================================

In EM (electron microscopy) crystallography, kinematic and quasi-kinematic approximations to the scattering of fast electrons allow for successfully solving and refining of unknown crystal structures, known as “structural electron crystallography”.

Crystalline specimens have to be tilted in a goniometer in TEM in order to:
         i) Observe lattice fringes and crystal structures.
         ii) Determine the crystal orientation.
         iii) Observe diffraction contrast of lattice defects with certain Bragg reflections or known orientation.
         iv) Determine the Burgers vector of lattice defects.
