First principles calculation (using Castep) of graphene (single planar sheet of
sp2-bonded carbon) and the adsorption thereon of atomic hydrogen. Chemisorption
of H2 is also studied. The implications for carbon nano-tubes are discussed.
Modulated graphene sheet containing a
Stone-Wales defect upon which H2 is dissociated. The sheet is
modulated to produce armchairlike curvature, and the maximum
curvature is equivalent to that of a (5,5) nanotube
