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…
Non-adiabatic Kohn Anomaly in Heavily Boron-doped Diamond
Fabio Caruso, Moritz Hoesch, Philipp Achatz +4
We report evidence of a non-adiabatic Kohn anomaly in boron-doped diamond, using a joint theoretical and experimental analysis of the phonon dispersion relations. We demonstrate th…
Element-Resolved Corrosion Analysis of Stainless-Type Glass-Forming Steels
M. J. Duarte, J. Klemm, S. O. Klemm +11
Ultrathin passive films effectively prevent the chemical attack of stainless steel grades in corrosive environments; their stability critically depends on the interplay between str…
Anisotropic excitonic effects in the energy loss function of hexagonal boron nitride
S. Galambosi, L. Wirtz, J. A. Soininen +7
We demonstrate that the valence energy-loss function of hexagonal boron nitride (hBN) displays a strong anisotropy in shape, excitation energy and dispersion for momentum transfer…
Phonon surface mapping of graphite: disentangling quasi--degenerate phonon dispersions
A. Grüneis, J. Serrano, A. Bosak +8
The two-dimensional mapping of the phonon dispersions around the point of graphite by inelastic x-ray scattering is provided. The present work resolves the longstanding issue r…
Disorder-induced phonon self-energy of semiconductors with binary isotopic composition
F. Widulle, J. Serrano, M. Cardona
Self-energy effects of Raman phonons in isotopically disordered semiconductors are deduced by perturbation theory and compared to experimental data. In contrast to the acoustic fre…
