Simultaneous Multi-Bragg Peak Coherent X-ray Diffraction Imaging

The simultaneous measurement of two Bragg reflections by coherent X-ray diffraction is demonstrated on a twinned Au crystal, which was prepared the solid-state dewetting 30 nm thin gold film sapphire substrate. crystal oriented goniometer so that lattice planes fulfill condition at same time. 111 and 200 peaks were measured simultaneously scanning energy incident beam recording patterns with two-dimensional detectors. While former reflection not sensitive to twin boundary, parallel crystal–substrate interface, latter only one part crystal. volume ratio between parts about 1:9, also confirmed Laue microdiffraction multiple essential for future in situ operando studies, are far limited either single or several series, facilitate precise monitoring both strain field defects during application external stimuli.
