摘要：
The effect of electron-phonon interaction in (8,0), (10,0) and (11,0) semiconducting single-walled carbon nanotubes on the band gap is investigated using the Holstein model and Green's function technique. By comparing numerical results for density of states without phonon modulation and with electron-phonon interaction, it is shown that the band gap decreases when coupling strength increases.
