Adsorption ofH2O,NH3, CO,NO2, and NO on graphene: A first-principles study

Open access
Leenaerts, O., Partoens, B., Peeters, F. M.·2008·Physical Review B

Abstract

Motivated by the recent realization of graphene sensors to detect individual gas molecules, we investigate the adsorption of ${\mathrm{H}}_{2}\mathrm{O}$, $\mathrm{N}{\mathrm{H}}_{3}$, CO, $\mathrm{N}{\mathrm{O}}_{2}$, and NO on a graphene substrate using first-principles calculations. The optimal adsorption position and orientation of these molecules on the graphene surface is determined and the adsorption energies are calculated. Molecular doping, i.e., charge transfer between the molecules and the graphene surface, is discussed in light of the density of states and the molecular orbitals of the adsorbates. The efficiency of doping of the different molecules is determined and the influence of their magnetic moment is discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
