Optically Induced Picosecond Lattice Compression in the Dielectric Component of a Strongly Coupled Ferroelectric/Dielectric Superlattice
Deepankar Sri Gyan, Hyeon Jun Lee, Youngjun Ahn +13
Above-bandgap femtosecond optical excitation of a ferroelectric/dielectric BaTiO3/CaTiO3 superlattice leads to structural responses that are a consequence of the screening of the s…
Variable-wavelength quick scanning nano-focused X-ray microscopy for in situ strain and tilt mapping
Marie-ingrid Richard, Thomas W Cornelius, Florian Lauraux +7
Compression of micro-pillars is followed in situ by a quick nano-focused X-ray scanning microscopy technique combined with three-dimensional reciprocal space mapping. Compared to o…
Precise wavefront characterization of X-ray optical elements using a laboratory source
J. L. Dresselhaus, H. Fleckenstein, M. Domaracky +7
Improvements in X-ray optics critically depend on the measurement of their optical performance. The knowledge of wavefront aberrations, for example, can be used to improve the fabr…
Statistical analysis of hard X-ray radiation at PAL-XFEL facility performed by Hanbury Brown and Twiss interferometry
Young Yong Kim, Ruslan Khubbutdinov, Jerome Carnis +11
Hanbury Brown and Twiss interferometry experiment based on second-order correlations was performed at PAL-XFEL facility. The statistical properties of the X-ray radiation were stud…
Spatially resolved fluorescence of caesium lead halide perovskite supercrystals reveals quasi-atomic behavior of nanocrystals
Dmitry Lapkin, Christopher Kirsch, Jonas Hiller +16
We correlate spatially resolved fluorescence (-lifetime) measurements with X-ray nanodiffraction to reveal surface defects in supercrystals of self-assembled caesium lead halide pe…
High spatial coherence and short pulse duration revealed by the Hanbury Brown and Twiss interferometry at the European XFEL
Ruslan Khubbutdinov, Natalia Gerasimova, Giuseppe Mercurio +16
Second-order intensity interferometry was employed to study the spatial and temporal properties of the European X-ray Free-Electron Laser (EuXFEL). Measurements were performed at t…
Structural Study of a Self-Assembled Gold Mesocrystal Grain by Coherent X-ray Diffraction Imaging
J. Carnis, F. Kirner, D. Lapkin +15
Mesocrystals are nanostructured materials consisting of individual nanocrystals having a preferred crystallographic orientation. On mesoscopic length scales, the properties of meso…
Single Alloy Nanoparticle X-Ray Imaging during a Catalytic Reaction
Young Yong Kim, Thomas F. Keller, Tiago J. Goncalves +8
The imaging of active nanoparticles represents a milestone in decoding heterogeneous catalysts dynamics. We report the facet resolved, surface strain state of a single PtRh alloy n…
PyNX: high performance computing toolkit for coherent X-ray imaging based on operators
Vincent Favre-Nicolin, Gaétan Girard, Steven Leake +5
The open-source PyNX toolkit [Favre-Nicolin et al (2011) arXiv:1010.2641, Mandula et al (2016)] has been extended to provide tools for coherent X-ray imaging data analysis and simu…
