| Abstract Scope |
Bragg Coherent Diffraction Imaging (BCDI) has been available for several years and there is clear potential for investigating mesoscale phenomena in materials science. The current coherence lengths of roughly 1 micron has motivated samples as varied as de-wetted films, deposits in vias and liftouts from bulk polycrystalline materials. Studying dislocation-boundary interactions has motivated multi-peak and more recently multi-grain reconstructions. It has also prompted development of polycrystal mapping, whether it be HEDM at high energies or Laue diffraction at medium energies. Recent results suggest that a multi-grain reconstruction of a matrix-twin-matrix 3-grain oligocrystal of gold on strontium titanate yields reasonable results that moreover suggest the presence of a dislocation in one of the grains. |
