Аннотация

We obtain a system of equations for the surface current density by taking the effect of intershell tunneling in the array of double-walled carbon nanotubes in the presence of a nonstationary electrical pulse into account. We show that if there is no tunneling, then the resonance frequency of surface currents for the symmetric mode increases by a factor of approximately √ 2 in addition to the twofold increase in their concentration in the direction transverse to the nanotube axis as compared with single-walled nanotubes. We show that bending the carbon nanotube surfaces does not affect the electrical conduction in the millimeter range of generated radiation. We discuss the influence of the nonstationary electrical pulse on the asymmetric mode of longitudinal surface currents.
