Experimental results show that there are unpredicted phenomena in the resistivity behavior of nanotubes as a function of their diameter. In this paper, the electrical resistivity behavior of carbon nanotubes (CNTs) is modeled as a function of diameter (at constant temperature) based on nanotube chirality. The effect of overlap of chirality surfaces on the resistivity of individual CNTs has been investigated and showed that if the windows of hexagonal lattice of individual CNTs face each other, the CNT resistivity increases. This effect becomes weaker if the diameter of nanotube increases. The proposed theoretical model explains the behavior of electrical resistivity of CNTs as a function of their diameters caused by chirality surface overlapping effect, and the obtained results are compared with the experimental reports.
