  Abstract:
Superconductivity in the single-walled carbon nanotubes is investigated. First, effect of diameter increasing on the clean systems critical temperature, Tc, is calculated. Then effect of impurity doping on the reduction of critical temperature Tc, of single-walled carbon nanotubes, is discussed. Our calculations illustrate that metallic zigzag single-walled carbon nanotubes have higher Tc than armchair single-walled carbon nanotubes with approximately same diameters and Tc decreases by increasing diameter. This can explain why superconductivity could be found in the small diameter single-walled carbon nanotubes. We found for the impurity doped systems, impurity in the strong scattering regime can decrease Tc significantly while in the weak scattering regime Tc is not affected by impurity doping
