First-principles studies of water adsorption on graphene: The role of the substrate
Tim O. Wehling, Mikhail I. Katsnelson, Alexander I. Lichtenstein
We investigate the electronic properties of graphene upon water adsorption and study the influence of the SiO2 substrate in this context using density functional calculations. Perf…
Phonon mediated tunneling into graphene
T. O. Wehling, I. Grigorenko, A. I. Lichtenstein +1
Recent scanning tunneling spectroscopy experiments [V. W. Brar et. al., Appl. Phys. Lett. 91, 122102 (2007), Y. Zhang et. al., arXiv:0802.4315 (2008)] on graphene reported an unexp…
Midgap states in corrugated graphene: Ab-initio calculations and effective field theory
T. O. Wehling, A. V. Balatsky, A. M. Tsvelik +2
We investigate the electronic properties of corrugated graphene and show how rippling-induced pseudomagnetic fields alter graphene's low-energy electronic properties by combining f…
Local impurity effects in superconducting graphene
T. O. Wehling, H. P. Dahal, A. I. Lichtenstein +1
We study the effect of impurities in superconducting graphene and discuss their influence on the local electronic properties. In particular, we consider the case of magnetic and no…
