AbstractThe electrical conductivity of ion beam irradiated Glassy Carbon has been investigated in the temperature range 100 to 300 K. Ion species used were C+ and N+ with doses between 1014 and 1018 ions/cm2. Ion beam irradiation was found to lower the conductivity of Glassy Carbon by up to six orders of magnitude. The temperature dependence of the conductivity in ion beam modified Glassy Carbon has been measured. The functional dependence was found to remain largely unchanged by ion irradiation despite the large overall decrease in the conductivity. The results are interpreted in terms of a model which includes a variable range hopping and strongly scattering metallic components.

The conductance properties of multi-walled carbon nanotube mats and their polystyrene composite were examined to investigate the mechanism of conduction and the specific role of the supporting polymer. By measuring the temperature dependence of the conductance, it was found that the conduction mechanism in carbon nanotube mat follows the series heterogeneous model when the conductance is described as the sum of metallic and barrier portions of the conduction path. This mechanism is affected by the polymeric portion of the composite, since the temperature dependence of the composite conductance is decreased.
