The intraband backward scattering by the longitudinal modes plays an important role for the occurrence of the superconducting state. Specifically for tube (5,5) with a diameter of ~7 Å, the Tc was found to be 1.5×10-4 K 关键词: electron-phonon interactions;fullerenes;superconducting transition temperature;superconducting transition temperature;metallic carbon nanotubes;electron-phonon interaction;intraband backward scattering;longitudinal modes;1.5E-4 K;C
