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…
High Resolution 3D Strain and Orientation Mapping within a Grain of a Directed Energy Deposition Laser Additively Manufactured Superalloy
Y. Chen, Y. T. Tang, D. M. Collins +8
The industrialization of Laser Additive Manufacturing (LAM) is challenged by the undesirable microstructures and high residual stresses originating from the fast and complex solidi…
Simultaneous Bright- and Dark-Field X-ray Microscopy at X-ray Free Electron Lasers
Leora E. Dresselhaus-Marais, Bernard Kozioziemski, Theodor S. Holstad +40
The structures, strain fields, and defect distributions in solid materials underlie the mechanical and physical properties across numerous applications. Many modern microstructural…
Extensive 3D Mapping of Dislocation Structures in Bulk Aluminum
Can Yildirim, Henning F. Poulsen, Grethe Winther +3
Thermomechanical processing such as annealing is one of the main methods to tailor the mechanical properties of materials, however, much is unknown about the reorganization of disl…
darfix: Data analysis for dark-field X-ray microscopy
Júlia Garriga Ferrer, Raquel Rodríguez-Lamas, Henri Payno +6
A Python package for the analysis of dark-field X-ray microscopy (DFXM) and rocking curve imaging (RCI) data is presented. \textit{darfix} provides a set of data processing and vis…
Simulating dark-field x-ray microscopy images with wave front propagation techniques
Mads Carlsen, Carsten Detlefs, Can Yildirim +2
Dark-Field X-ray Microscopy (DFXM) is a diffraction-based synchrotron imaging techique capable of imaging defects in the bulk of extended crystalline samples. We present numerical…
In-Situ Visualization of Long-Range Defect Interactions at the Edge of Melting
Leora E. Dresselhaus-Marais, Grethe Winther, Marylesa Howard +9
Connecting a bulk material's microscopic defects to its macroscopic properties is an age-old problem in materials science. Long-range interactions between dislocations (line defect…
Universal amorphous-amorphous transition in GexSe1-x glasses under pressure
Can Yildirim, Matthieu Micoulaut, Punit Boolchand +5
Pressure induced structural modifications in vitreous GeSe (where 10 x 25)are investigated using X-ray absorption spectroscopy (XAS) along with supple…
