Evolution of ordered nanoporous phases during h-BN growth: Controlling the route from gas-phase precursor to 2D material by monitoring
Adrian Ruckhofer, Marco Sacchi, Anthony Payne +4
Large-area single-crystal monolayers of two-dimensional (2D) materials such as graphene and hexagonal boron nitride (h-BN) can be grown by chemical vapour deposition (CVD). However…
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…
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…
How Atomic Steps Modify Diffusion and Inter-adsorbate Forces: Empirical Evidence From Hopping Dynamics in Na/Cu(115)
O. Godsi, G. Corem, T. Kravchuk +7
We followed the collective atomic-scale motion of Na atoms on a vicinal Cu(115) surface within a time scale of pico to nano-seconds using helium spin echo spectroscopy. The well de…
