Dynamical Scattering in Coherent Hard X-Ray Nanobeam Bragg Diffraction

26 Feb 2020 Pateras A. Park J. Ahn Y. Tilka J. A. Holt M. V. Kim H. Mawst L. J. Evans P. G.

Unique intensity features arising from dynamical diffraction arise in coherent x-ray nanobeam diffraction patterns of crystals having thicknesses larger than the x-ray extinction depth or exhibiting combinations of nanoscale and mesoscale features. We demonstrate that dynamical scattering effects can be accurately predicted using an optical model combined with the Darwin theory of dynamical x-ray diffraction... (read more)
