Inter-adsorbate forces and coherent scattering in helium spin-echo experiments
David J. Ward, Arjun Raghavan, Anton Tamtögl +5
In studies of dynamical systems, helium atoms scatter coherently from an ensemble of adsorbates as they diffuse on the surface. The results give information on the co-operative beh…
Origin of the Electron-Phonon Interaction of Topological Semimetal Surfaces Measured with Helium Atom Scattering
G. Benedek, S. Miret-Artés, J. R. Manson +3
He atom scattering has been demonstrated to be a sensitive probe of the electron-phonon interaction parameter at metal and metal-overlayer surfaces. Here it is shown that the t…
Nanoscale Surface Dynamics of BiTe(111): Observation of a Prominent Surface Acoustic Wave and the Role of van der Waals Interactions
Anton Tamtögl, Davide Campi, Martin Bremholm +8
We present a combined experimental and theoretical study of the surface vibrational modes of the topological insulator BiTe. Using high-resolution helium-3 spin-echo spectr…
A Helium-Surface Interaction Potential of BiTe(111) from Ultrahigh-Resolution Spin-Echo Measurements
Anton Tamtögl, Michael Pusterhofer, Martin Bremholm +7
We have determined an atom-surface interaction potential for the HeBiTe(111) system by analysing ultrahigh resolution measurements of selective adsorption resonances. Th…
