Coating the carbon nanotubes: Geometry of incommensurate long-range ordered physisorbed monolayers

摘要

The structures of long-range ordered physisorbed monolayer on a carbonnanotube are examined. Geometrical and energetical constraints determining theorder of such monolayers are discussed. A number of symmetrically different,strongly bound adsorbate structures is found for Xe adsorbates, some of whichdiffer very little in energy. The presented results suggest that the atomicallyuniform coating of carbon nanotubes is possible and offer a clear visualizationof such coatings.
