High-Quality Ultra-Fast Total Scattering and Pair Distribution Function Data using an X-ray Free Electron Laser

Adam F. Sapnik, Philip A. Chater, Dean S. Keeble +48

High-quality total scattering data, a key tool for understanding atomic-scale structure in disordered materials, require stable instrumentation and access to high momentum transfer…

Recovery of harmonic-like behaviour of the polar mode in BaTiO at high pressure

A. Herlihy, T. A. Bird, C. J. Ridley +3

The local structure of high pressure BaTiO has been interrogated by neutron total scattering methods, up to pressures of 4.18 GPa at ambient temperature. Competitive refinement…

Large dynamic scissoring mode displacements coupled to band gap opening in Hybrid Perovskites

Tobias A. Bird, Jungshen Chen, Manila Songvilay +4

Hybrid perovskites are a rapidly growing research area, having reached photovoltaic power conversion efficiencies of over 25 \%. We apply a symmetry-motivated analysis method to an…

Soft mode anisotropy in negative thermal expansion material ReO

Tobias A. Bird, Mark G. L. Wilkinson, David A. Keen +5

We use a symmetry-motivated approach to analyse neutron pair distribution function data to investigate the mechanism of negative thermal expansion (NTE) in ReO. This analysis s…

Anharmonicity and scissoring modes in the negative thermal expansion materials ScF and CaZrF

Tobias Bird, Jessica Woodland-Scott, Lei Hu +4

We use a symmetry-motivated approach to analysing X-ray pair distribution functions to study the mechanism of negative thermal expansion in two ReO-like compounds; ScF and…
