Ab initio study of the effect of H2O molecules adsorption on the semiconducting graphene nanoribbon

Abstract

The H2O molecules adsorption effects over electronic transport properties of Armchair Graphene Nanoribbons (A-GNR) was theoretically studied using Non Equilibrium Green Function (NEGF) formalism along with Ab initio calculation. Three different orientations and adsorption sites are considered to calculate the adsorption energies. The calculated adsorption energies for those orientations also suggest that adsorption in metallic A-GNR has much smaller effect on its transport properties.
