Operando study of the evolution of peritectic structures in metal solidification by quasi-simultaneous synchrotron X-ray diffraction and tomography
Kang Xiang, Yueyuan Wang, Shi Huang +8
Using quasi-simultaneous synchrotron X-ray diffraction and tomography techniques, we have studied in-situ and in real-time the nucleation and co-growth dynamics of the peritectic s…
Substrate pre-sputtering for layer-by-layer van der Waals epitaxy of 2D materials
A. Rajan, M. Ramirez, N. Kushwaha +3
Two-dimensional transition metal chalcogenides, with their atomically layered structure, favourable electronic and mechanical properties, and often strong spin-orbit coupling, are…
Persistence of charge ordering instability to Coulomb engineering in the excitonic insulator candidate TiSe
Sebastian Buchberger, Yann in 't Veld, Akhil Rajan +11
TiSe has long been considered one of the best candidate materials to host the elusive excitonic insulator (EI) phase. However, a finite coupling to the lattice can generically…
From ferromagnetic semiconductor to anti-ferromagnetic metal in epitaxial CrTe monolayers
Naina Kushwaha, Olivia Armitage, Brendan Edwards +6
Chromium ditelluride, CrTe, is an attractive candidate van der Waals material for hosting 2D magnetism. However, how the room-temperature ferromagnetism of the bulk evolves as…
Disorder Driven Non-Anderson Transition in a Weyl Semimetal
Cong Li, Yang Wang, Jianfeng Zhang +11
For several decades, it was widely believed that a non-interacting disordered electronic system could only undergo an Anderson metal-insulator transition due to Anderson localizati…
In-situ exfoliation method of large-area 2D materials
Antonija Grubišić-Čabo, Matteo Michiardi, Charlotte E. Sanders +6
The success in studying 2D materials inherently relies on producing samples of large area, and high quality enough for the experimental conditions. Because their 2D nature surface…
Tracking the surface atomic motion in a coherent phonon oscillation
Davide Curcio, Klara Volckaert, Dmytro Kutnyakhov +10
X-ray photoelectron diffraction is a powerful tool for determining the structure of clean and adsorbate-covered surfaces. Extending the technique into the ultrafast time domain wil…
Evaluation of the Thermal Stability of TiW/Cu Heterojunctions Using a Combined SXPS and HAXPES Approach
Curran Kalha, Michael Reisinger, Pardeep. K. Thakur +7
Power semiconductor device architectures require the inclusion of a diffusion barrier to suppress, or at best prevent the interdiffusion between the copper metallisation interconne…
Thallium under extreme compression
C. Cazorla, S. G. MacLeod, D. Errandonea +3
We present a combined theoretical and experimental study of the high-pressure behavior of thallium. X-ray diffraction experiments have been carried out at room temperature up to 12…
Coherent X-ray measurements of ion-implantation-induced lattice strains in nano-crystals
Felix Hofmann, Edmund Tarleton, Ross J. Harder +6
Focussed Ion Beam (FIB) milling is a mainstay of nano-scale machining. By manipulating a tightly focussed beam of energetic ions, often gallium (Ga+), FIB can sculpt nanostructures…
Compositional dependence of anomalous thermal expansion in perovskite-like ABX3 formates
Ines E. Collings, Joshua A. Hill, Andrew B. Cairns +5
The compositional dependence of thermal expansion behaviour in 19 different perovskite-like metal-organic frameworks (MOFs) of composition [AI][MII(HCOO)3] (A = alkylammonium catio…
One-dimensional chain "melting" in incommensurate potassium
Emma E. McBride, Keith A. Munro, Graham W. Stinton +4
Between 19 and 54 GPa, potassium has a complex composite incommensurate host-guest structure which undergoes two intraphase transitions over this pressure range. The temperature de…
Direct observation of ultrafast long-range charge separation at polymer:fullerene heterojunctions
Françoise Provencher, Nicolas Bérubé, Anthony W. Parker +7
In polymeric semiconductors, charge carriers are polarons, which means that the excess charge deforms the molecular structure of the polymer chain that hosts it. This effect result…
Intermediate range order in (Fe,Al) silicate network glasses: a neutron diffraction and EPSR modeling investigation
Coralie Weigel, Laurent Cormier, Georges Calas +2
The local structural environment and the spatial distribution of iron and aluminum ions in sodosilicate glasses with composition NaFexAl1-xSi2O6 (x = 1, 0.8, 0.5 and 0) is studied…
Nature of the bound states of molecular hydrogen in carbon nanohorns
Felix Fernandez-Alonso, F. Javier Bermejo, Carlos Cabrillo +3
The effects of confining molecular hydrogen within carbon nanohorns are studied via high-resolution quasielastic and inelastic neutron spectroscopies. Both sets of data are remarka…
