This chapter reviews nonresonant, meV-resolution inelastic x-ray scattering (IXS), as applied
to the measurement of atomic dynamics of crystalline materials. It, in conjunction with a …

The microscopic origin of the large negative thermal expansion of cubic scandium
trifluorides (ScF 3) is investigated by performing a set of anharmonic free-energy …

Using calculations of the phonon distribution in ScF3 across the whole of reciprocal space,
we show that the important phonons for the negative thermal expansion in this material are …

This paper reviews non-resonant, meV-resolution inelastic x-ray scattering (IXS), as applied
to the measurement of atomic dynamics of crystalline materials. It is designed to be an …

We examine the effects of strain and cation substitution on the superconducting phase of
polar semiconductors near a ferroelectric quantum phase transition with a model that …

Scandium trifluoride is a model negative thermal expansion (NTE) material. Its simple
structure can be described as an A-site vacant perovskite, and it shows isotropic NTE over a …

Discovering new negative thermal expansion (NTE) materials is a great challenge in
experiment. Meanwhile, the machine learning (ML) method can be another approach to …

Negative thermal expansion is an unusual phenomenon appearing in only a handful of
materials, but pursuit and mastery of the phenomenon holds great promise for applications …

Cubic ReO3-type fluorides often display negative or very low thermal expansion. However,
they also typically undergo phase transitions upon cooling and/or modest compression …

Negative thermal expansion (NTE) describes the anomalous propensity of materials to
shrink when heated. Since its discovery, the NTE effect has been found in a wide variety of …
