Molecular physisorption on graphene and carbon nanotubes: A comparative ab initio study

Abstract

The results of ab initio density functional theory calculations of molecular physisorption on a number of different adsorption sites on a graphene sheet and on a (10, 0) single walled carbon nanotube are discussed. Both the Vosko-Wilk-Nusair (VWN) local density approximation (LDA) functional and the Perdew-Wang (PW91) generalized gradient approximation (GGA… (More)
