Time-resolved coherent X-ray diffraction imaging of surface acoustic waves

The time-dependent one-dimensional height profile of a standing surface acoustic wave on an LiNbO₃ substrate has been reconstructed from stroboscopically recorded coherent grazing-incidence small-angle diffraction patterns.

Double hexagonal close-packed structure revealed in a single colloidal crystal grain by Bragg rod analysis

Analysis of the Bragg rod intensity fluctuations present in the coherent X-ray scattering data from a 4 µm single colloidal crystal grain reveals the presence of a double hexagonal close-packed stacking sequence.
