Charge distribution of metallic single walled carbon nanotube–graphene junctions

open access: yesNew Journal of Physics, 2014
We report numeric and analytic calculations of the electrostatic properties for armchair carbon nanotube–graphene junctions. Using a semi-empirical method we first demonstrate that the equilibrium distance between a carbon nanotube and a graphene sheet ...

Paraconductivity in carbon nanotubes [PDF]

open access: yesPhysical Review B, 2002
We report the calculation of paraconductivity in carbon nanotubes above the superconducting transition temperature. The complex behavior of paraconductivity depending upon the tube radius, temperature and magnetic field strength is analyzed. The results are qualitatively compared with recent experimental observations in carbon nanotubes of an inherent ...
