Scientific Achievement
Three-dimensional nanoscale imaging of vector-valued lattice displacement fields in crystals was demonstrated via an optimization-based inversion approach for multi-reflection Bragg coherent diffraction imaging (MR-BCDI).
Significance and Impact
This achievement will enable efficient imaging of lattice defects and heterogeneities that govern the behavior of nanoparticles, and it paves the way for in-situ studies at APS-U with high-throughput in-situ MR-BCDI.
Research Details
- A model of MR-BCDI diffraction was developed that accounts for the geometric factors of realistic measurements and that is amenable to inversion with global optimization.
- This MR-BCDI approach was used to visualize an internal lattice displacement vector field within a SiC nanoparticle fabricated by methods used to make quantum sensors.
