dc.description.abstract | have investigated hydrogenated single-wall armchair (n,n) carbon nanotubes (CNTs) with 4 <= n <= 12 by using density functional theory calculations. Hydrogen adsorption may transform the CNTs into a horseshoe shape. Nonmagnetic edge-localized electron states have been identified in CNTs of horseshoe shape in this work. The sigma-bond-like orbital overlaps across the edge-localized electrons, which sustain the horseshoe shape of the CNTs and hinder spontaneous unravelling into a graphene nanoribbon, cause the horseshoe-shape CNTs to become nonmagnetic metal. The bonding energy between the hydrogenated edges increases with the CNT diameter, approaching a limit of similar to 1 eV. | - |
