      abstract     = {It is shown that higher order Laue zone (HOLZ) rings in
                      high energy electron diffraction are specific to individual
                      columns of atoms, and show different strengths, structure
                      and radii for different atom columns along the same
                      projection in a structure. An atomic resolution
                      4-dimensional STEM dataset is recorded from a <110>
                      direction in a perovskite trilayer, where only the central
                      LaFeO3 layer should show a period doubling that gives rise
                      to an extra HOLZ ring. Careful comparison between experiment
                      and multislice simulations is used to understand the origins
                      of all features in the patterns. A strong HOLZ ring is seen
                      for the La-O columns, indicating strong La position
                      modulation along this direction, whereas a weaker ring is
                      seen along the O columns, and a very weak ring is seen along
                      the Fe columns. This demonstrates that atomic resolution
                      HOLZ-STEM is a feasible method for investigating the 3D
                      periodicity of crystalline materials with atomic
                      resolution.},
