Understanding irradiation assisted hydrogen embrittlement using in situ BCDI.

Ericmoore JOSSOU · Jiangtao ZHAO · David SIMONNE · Sayantan MONDAL · y 2 más

This proposal describes the use of BCDI at the ID01 beamline to understand the radiation-assisted hydrogen embrittlement (HE) mechanism in Fe and Fe-Cr model single crystals, prepared by dewetting. Three-dimensional coherent X-ray diffraction patterns will be used to image the hydrogen-induced strain, and to quantify t...

Confinement effects on magnetic excitations in cuprate superconductors

Giacomo MERZONI · Marco MORETTI · RICCARDO ARPAIA · Giacomo GHIRINGHELLI · y 3 más

The role of spin excitations in the formation of Cooper pairs in high-temperature cuprate superconductors is still controversial. Our recent RIXS measurements at the ESRF reported anomalies in the magnon peak shape for YBCO thin films cut along the (103) crystal surface compared to c-axis oriented films. At present, it...

XAS investigations of local atomic and bonding properties in liquid Ge under shock compression

Angelika ROSA · Emanuele COLONNA · Samuel GALLEGO PARRA · Nicolas SEVELIN-RADIGUET · y 3 más

Elemental Ge is one of the archetypal single component substances extensively studied over the years for exploring the behavior of liquid-liquid transitions. Nevertheless, the low-density semiconducting liquid observed in computer simulations yet to be experimentally observed for non-ambiguous interpretations of the pr...

Anisotropy of the ultrafast Mott insulator-to-metal transition in the quantum material V2O3: towards a global physical picture

Elzbieta TRZOP · Etienne JANOD · LUDOVIC DURAN NGOUNOU · Marina SERVOL · y 4 más

Building on our discovery that ultrafast photoinduced Mott insulator-to-metal transitions (IMT) in V2O3 are driven by strain waves [T. Amano et al., Nature Physics (2024), accepted], this proposal aims to explore how crystal orientation and size influence these transitions using Focused Ion Beam technology. We will emp...

GaAs/GaInP nano-ridges: strain relaxation for III-V integration on Si wafers

JOEL EYMERY · Jean-Sebastien MICHA

The proposed experiment focuses on studying strain relaxation and defect formation in GaAs/InGaP and GaAs/InGaAs nano-ridge (NR) structures grown on Si wafers using μLaue technique. The integration of III-V semiconductors with Si substrates via Nano-Ridge Engineering (NRE) enables applications such as heterojunction bi...

The European Battery Hub

Gabriele D'AIUTO · Sandrine LYONNARD · Lorenzo STIEVANO · Soumik KUMAR · y 6 más

This project is the continuation of the Battery Pilot Hub (MA4929), a pioneer initiative at ESRF designed to achieve large-scale synchrotron-based correlative characterization of battery materials (2021-24). The European Battery Hub is the demonstrator of this new community-driven approach, where we will develop, expan...

Multiple Testing of Local Extrema for Detection of Structural Breaks in Piecewise Linear Models

He, Zhibing · Cheng, Dan · Zhao, Yunpeng

In this paper, we propose a new generic method for detecting the number and locations of structural breaks or change points in piecewise linear models under stationary Gaussian noise. Our method transforms the change point detection problem into identifying local extrema (local maxima and local minima) through kernel s...

Advancing 4D Imaging: Pink Beam DFXM and 3DXRD at ESRF's ID03

ADITYA SHUKLA · Virginia SANNA · LOUIS LESAGE · MICHELA LA BELLA · y 3 más

In the past seven years, the PI, in collaboration with ID06-HXM staff and the DTU, has led advancements in DFXM achieving 100 nm resolution in 3D imaging of crystalline materials. Despite its success, DFXM needs significant improvements for mapping deformation and grain interaction. This LTP, part of an ERC-funded proj...
