Bragg coherent modulation imaging of indented Pt nanocrystals

The detection of crystal defect/dislocation evolution is great significant to reveal the micromechanical properties of crystals. However, current Bragg coherent diffraction imaging is difficult to handle the measurement of complex or highly strained crystal systems. In this proposal, we will use Bragg coherence modulation imaging, an advanced method for measuring highly strained nanocrystals, to detect defects/dislocations and strain states inside the crystal under different indentation pressures. The success of this experiment will correlate crystal defects/dislocations and micromechanical properties.
