Understanding ultrafast x-ray 'echoes' diffracted from single crystals
Angel Rodriguez-Fernandez, Dmitry Karpov, Steven Leake +2
Multiple x-ray beams generated by interference processes in perfect crystals were imaged with a resolution of about 100nm using tele-ptychography in the diffraction direction. Thes…
Electric Field Driven Domain Wall Dynamics in BaTiO3 Nanoparticles
Jialun Liu, David Yang, Ana F. Suzana +2
We report a detailed investigation into the response of single BaTiO3 (BTO) nanocrystals under applied electric fields (E-field) using Bragg Coherent Diffraction Imaging (BCDI). Ou…
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…
Imaging the Breathing of a Platinum Nanoparticle in Electrochemical Environment
Clément Atlan, Corentin Chatelier, Maxime Dupraz +9
Surface strain is widely used in gas phase catalysis and electrocatalysis to control the binding energies of adsorbates on metal surfaces. However, or strain…
A convolutional neural network for defect classification in Bragg coherent X-ray diffraction
Bruce Lim, Ewen Bellec, Maxime Dupraz +8
Coherent diffraction imaging enables the imaging of individual defects, such as dislocations or stacking faults, in materials.These defects and their surrounding elastic strain fie…
Bragg Coherent Imaging of nanoprecipitates: role of superstructure reflections
Maxime Dupraz, Steven J. Leake, Marie-Ingrid Richard
Coherent precipitation of ordered phases is responsible for providing exceptional high temperature mechanical properties in a wide range of compositionally complex alloys (CCAs). O…
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…
Free log-likelihood as an unbiased metric for coherent diffraction imaging
Vincent Favre-Nicolin, Steven Leake, Yuriy Chushkin
Coherent Diffraction Imaging (CDI), a technique where an object is reconstructed from a single (2D or 3D) diffraction pattern, recovers the lost diffraction phases without a priori…
Chemistry and structure of homoepitaxial SrTiO films and their influence on oxide-heterostructure interfaces
M. L. Reinle-Schmitt, C. Cancellieri, A. Cavallaro +4
The properties of single-crystal SrTiO substrates and homoepitaxial SrTiO films grown by pulsed laser deposition have been compared, in order to understand the loss of…
Evolution of the interfacial structure of LaAlO3 on SrTiO3
S. A. Pauli, S. J. Leake, B. Delley +7
The evolution of the atomic structure of LaAlO3 grown on SrTiO3 was investigated using surface x-ray diffraction in conjunction with model-independent, phase-retrieval algorithms b…
