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…
Version 0: An Educational Package for Helium Atom Scattering Studies
Ethan L. Arnold, Ming-Shau Liu, Rohit Prabhu +3
Helium atom scattering studies have the potential for making numerous breakthroughs in the study of processes on surfaces. As this field remains active, there will frequently be ne…
Motion of water monomers reveals a kinetic barrier to ice nucleation on graphene
Anton Tamtögl, Emanuel Bahn, Marco Sacchi +7
The interfacial behaviour of water remains a central question to fields as diverse as protein folding, friction and ice formation[1,2]. While the structural and dynamical propertie…
Polarisation in Spin-Echo Experiments: Multi-point and Lock-in Measurements
Anton Tamtögl, Benjamin Davey, David J. Ward +3
Spin-echo instruments are typically used to measure diffusive processes and the dynamics and motion in samples on ps and ns timescales. A key aspect of the spin-echo technique is t…
Energy Dissipation during Diffusion at Metal Surfaces: Disentangling the Role of Phonons vs. Electron-Hole Pairs
Simon P. Rittmeyer, David J. Ward, Patrick Gütlein +3
Helium spin echo experiments combined with ab initio-based Langevin molecular dynamics simulations are used to quantify the adsorbate-substrate coupling during the thermal diffusio…
