    Abstract

    We measured and analysed the electronic transport properties of a single-walled carbon nanotube (SWCNT) network on which the nanotubes were deposited by an ink-jet method. The SWCNT network showed an Ohmic behaviour down to a temperature T of 0.5 K. Moreover, the resistance of the SWCNT network exhibited a temperature dependence which indicated a Mott variable-range hopping transport mechanism. A localisation length was extracted and estimated to be between 3.6 and 11 nm; this indicated that the SWCNT sample constituted a 3D network. The magnetoresistance reached a minimum for a certain value of the magnetic field B min. With decreasing the temperature, B min tended linearly to 0 T. This observation was interpreted as the suppression of a quantum interference process between electronic hopping paths through neighbouring defects of the SWCNT network.
