Abstract
This research details electronic and magneto-transport in unsorted and chirality-enriched carbon nanotube (CNT) films. By measuring electrical conductivity from 4 K to 297 K we were able to assign the governing mechanism of electronic transport. Fluctuation-Induced Tunnelling was in accordance with the obtained data and very well matched the underlying physics. We demonstrated how a change in the type of CNT to make the film affects its electrical performance. As the temperature was decreased down to cryogenic conditions, up to 56 fold increase in resistance was noted. Moreover, measurement of magnetoresistance (MR) revealed non-monotonic dependence on the applied magnetic field. Initial negative component of MR was eventually overpowered by the positive MR component as the field strength was increased beyond a certain threshold.
