Lattice dynamics and elastic properties of black phosphorus
Eva A. A. Pogna, Alexeï Bosak, Alexandra Chumakova +4
We experimentally determine the lattice dynamics of black phosphorus layered crystals through a combination of x-ray diffuse scattering and inelastic x-ray scattering, and we ratio…
Strain Wave Pathway to Semiconductor-to-Metal Transition revealed by time resolved X-ray powder diffraction
C. Mariette, M. Lorenc, H. Cailleau +42
Thanks to the remarkable developments of ultrafast science, one of today's challenges is to modify material state by controlling with a light pulse the coherent motions that connec…
Archetypal soft-mode driven antipolar transition in francisite Cu3Bi(SeO3)2O2Cl
Cosme Milesi-Brault, Constance Toulouse, Evan Constable +8
Model materials are precious test cases for elementary theories and provide building blocks for the understanding of more complex cases. Here, we describe the lattice dynamics of t…
Lattice dynamics and phase stability of rhombohedral antimony under high pressure
Arianna Minelli, Sofia Michaela Souliou, Tra Nguyen-Thanh +6
The high pressure lattice dynamics of rhombohedral antimony have been studied by a combination of diffuse scattering and inelastic x-ray scattering. The evolution of the phonon beh…
Full elasticity tensor from thermal diffuse scattering
Björn Wehinger, Alessandro Mirone, Alexeï Bosak +1
We present a method for the precise determination of the full elasticity tensor from a single crystal diffraction experiment using monochromatic X-rays. For the two benchmark syste…
First principles calculation and experimental investigation of lattice dynamics in the rare earth pyrochlores R2Ti2O7 (R=Tb, Dy, Ho)
M Ruminy, M Nunez Valdez, B Wehinger +15
We present a model of the lattice dynamics of the rare earth titanate pyrochlores R2Ti2O7 (R=Tb, Dy, Ho), which are important materials in the study of frustrated magnetism. The ph…
