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…
Multilayer Laue Lenses for Enhanced Spatial Resolution in Dark-Field X-ray Microscopy
Steffen Staeck, Can Yildirim, Raquel Rodriguez-Lamas +5
We introduce the use of a crossed pair of Multilayer Laue Lenses (MLLs) as an objective in Dark-Field X-ray Microscopy (DFXM). In a demonstration experiment at the ID03 beamline at…
Unexpected Planar Dislocation Boundary Formation in FCC Metals Captured by Dark-Field X-ray Microscopy and Continuum Dislocation Dynamics
Adam André William Cretton, Khaled SharafEldin, Axel Henningsson +8
Validating dislocation patterning models against in situ imaging experiments is a longstanding goal in materials physics. Here, we provide the first direct morphological comparison…
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…
Oblique diffraction geometry for the observation of several non-coplanar Bragg reflections under identical illumination
C. Detlefs, A. Henningsson, B. Kanesalingam +9
We present a method to determine the strain tensor and local lattice rotation with Dark Field X-ray Microscopy. Using a set of at least 3 non-coplanar, symmetry-equivalent Bragg re…
