Abstract

In many IV measurements an evidence has emerged pointing towards the existence of Luttinger liquid behavior in metallic SWNT, as expected for strongly interacting electrons in 1-d, such behavior was observed via the power law temperature and biasvoltage dependence of the current through tunneling contacts attached to the nanotubes. In particular recent advances in the growth of extremely long nanotube ( >1 mm) have allowed for experimental measurements on the scaling behavior of resistance in individual, millimeter long SWNT for the temperature range of 1.6-300 K. From the linear scaling of resistance, the temperature dependent electron mean free path has been calculated for each temperature and, beyond the linear scaling regime, it has been observed that the resistance increases exponentially with length, indicating localization behavior. In this work we analyse the results of the resistance measurements of different lengths SWNT indicating the weak localization behavior.
