Journal ArticleDOI
Migration of a carbon adatom on a charged single-walled carbon nanotube
TL;DR: In this paper, negative charges on an armchair single-walled carbon nanotube (SWCNT) can significantly enhance the migration of a carbon adatom on the external surfaces of SWCNTs, along the direction of the tube axis.
Journal ArticleDOI
First-principles free-energy calculations on condensed-matter systems: Lattice vacancy in silicon.
Enrico Smargiassi,Roberto Car +1 more
TL;DR: It is shown that the method can be used in cases in which electrons have to be decoupled from the system and illustrated with results for the formation free energy of the Si vacancy.
Journal ArticleDOI
Stability of two-dimensional nanostructures
Karina Morgenstern,Erik Lægsgaard,Ivan Stensgaard,Flemming Besenbacher,Matthias Böhringer,Wolf-Dieter Schneider,Richard Berndt,Francesco Mauri,A. De Vita,Roberto Car +9 more
TL;DR: In this paper, the authors investigate atomic and molecular nanostructures on metal surfaces by variable low-temperature scanning tunnelling microscopy and achieve a detailed understanding of the stability of these structures.
Journal ArticleDOI
Theory of tunneling transport in periodic chains
Emil Prodan,Roberto Car +1 more
TL;DR: In this article, an analytic formula for the asymptotic tunneling conductance involving the overlap of three well-defined physical quantities that can be easily evaluated with the standard electronic structure codes is presented.
Journal ArticleDOI
Hydrogen Dynamics in Supercritical Water Probed by Neutron Scattering and Computer Simulations.
Carla Andreani,Giovanni Romanelli,A. Parmentier,Roberto Senesi,Alexander I. Kolesnikov,Hsin-Yu Ko,Marcos F. Calegari Andrade,Roberto Car +7 more
TL;DR: Results show that the local potential affecting hydrogen becomes less anisotropic within the molecular plane in the supercritical phase, and this result is attributed to the presence of more distorted hydrogen bonds.
