| Abstract | We present ab initio calculations of electron‐phonon coupling in single‐walled nanotubes and graphene. The perturbation of the electronic energies due to the atomic distortion caused by totally symmetric phonons was calculated, yielding the matrix elements of the electron‐phonon interaction. For the radial breathing mode (RBM) we obtained a decrease of the electron‐phonon interaction with increasing diameter. This is in good agreement with the fact that the equivalent mode for graphene is an out‐of‐plane translation which cannot affect the electronic system. The matrix elements for the RBM and the optical A1g mode show different behaviours for armchair and zig‐zag nanotubes. |
