Understanding the anomalously low dielectric constant of confined water: an ab initio study
Thomas Dufils, Christoph Schran, Ji Chen +3
Recent experiments have shown that the out-of-plane dielectric constant of water confined in nanoslits of graphite and hexagonal boron nitride (hBN) is vanishingly small. Despite e…
Quantum tunnelling driven H formation on graphene
Erxun Han, Wei Fang, Michail Stamatakis +2
It is commonly believed that it is unfavourable for adsorbed H atoms on carbonaceous surfaces to form H without the help of incident H atoms. Using ring-polymer instanton theor…
The quantum nature of hydrogen
Wei Fang, Ji Chen, Yexin Feng +2
Hydrogen is the most abundant element in the universe. It is also the lightest and as such the most quantum of the elements, in the sense that quantum tunnelling, quantum delocalis…
Simultaneous Deep Tunneling and Classical Hopping for Hydrogen Diffusion on Metals
W. Fang, J. O. Richardson, J. Chen +2
Hydrogen diffusion on metals exhibits rich quantum behavior, which is not yet fully understood. Using simulations, we show that many hydrogen diffusion barriers can be categorized…
