We report the doping dependence of the transport properties of single walled carbon nanotube (SWNT) films doped with organic molecules in the low temperature. The temperature dependence of the resistance and the magnetoresistance of SWNT films are investigated systematically, and well explained by two-dimensional variable range hopping (2D-VRH) conduction scheme. We found that the magnetoresistance is dramatically reduced upon doping, and analysis based on 2D-VRH theory revealed that the sheet density of states at the Fermi level showed monotonic increase with increasing of carrier density. These results indicate that the carrier hopping in SWNT film is enhanced by the carrier doping.
