High energy-resolution transient ghost absorption spectroscopy
Alok Kumar Tripathi, Yishai Klein, Edward Strizhevsky +10
We demonstrate the measurement of ultrafast dynamics using ghost spectroscopy and a pump-probe approach with an optical pump and a short-wavelength radiation probe. The ghost spect…
Influence of Contacts and Applied Voltage on a Structure of a Single GaN Nanowire
Sergey Lazarev, Luca Gelisio, Young Yong Kim +11
Semiconductor nanowires (NWs) have a broad range of applications for nano- and optoelectronics. The strain field of gallium nitride (GaN) NWs could be significantly changed when co…
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…
An advanced workflow for single particle imaging with the limited data at an X-ray free-electron laser
Dameli Assalauova, Young Yong Kim, Sergey Bobkov +25
An improved analysis for single particle imaging (SPI) experiments, using the limited data, is presented here. Results are based on a study of bacteriophage PR772 performed at the…
Gas-induced segregation in Pt-Rh alloy nanoparticles observed by in-situ Bragg coherent diffraction imaging
Tomoya Kawaguchi, Thomas F. Keller, Henning Runge +11
Bimetallic catalysts can undergo segregation or redistribution of the metals driven by oxidizing and reducing environments. Bragg coherent diffraction imaging (BCDI) was used to re…
