摘要：

Using a scattering technique, combined with density-functional theory, a computational study of the electron-transport properties of multiwall carbon nanotube (MWNT) telescopes and shuttles is presented. When the inner nanotube of a MWNT is displaced by an amount deltax with respect to the outer tube, we predict that the interwall pi-pi coupling, gamma(pi-pi), is significantly modified, leading to unexpected conductance oscillations for values of deltax of the order of the interatomic spacing. An analytical model is presented, which provides a mapping between gamma(pi-pi) and electron-transport measurements.
