Automated Burgers Vector Identification for Individual Dislocations in Bulk Crystals
Abderrahmane Benhadjira, Carsten Detlefs, Vincent Favre-Nicolin +4
Weak-beam imaging in dark-field X-ray microscopy (DFXM) can resolve individual dislocations in bulk crystals, but assigning Burgers vectors from the resulting contrast typically re…
Spatially resolved elastic strain and lattice rotation at threading dislocations in HgCdTe/CdZnTe epilayers by dark-field X-ray microscopy
C. Yildirim, A. Benhadjira, P. Ballet +5
Threading dislocations (TDs) propagating from a CdZnTe (CZT) substrate into a liquid-phase-epitaxy HgCdTe (MCT) epilayer set the minority-carrier lifeti…
3D Mapping of Intragranular Residual Strain and Microstructure in Recrystallized Iron Using Dark-Field X-ray Microscopy
Virginia Sanna, Yubin Zhang, Wolfgang Ludwig +4
Grain growth is a key process in the thermomechanical treatment of metals. Recently, the presence of local residual stresses within fully recrystallized grains has attracted increa…
Deep Learning-Assisted Weak Beam Identification in Dark-Field X-ray Microscopy
A. Benhadjira, C. Detlefs, S. Borgi +2
Dislocations control the mechanical behavior of crystalline materials, yet their quantitative characterization in bulk has remained elusive. Transmission Electron Microscopy provid…
