In this paper, we focus on currentâ€“voltage (Iâ€“V) characteristics in several kinds of quasi-one-dimensional (quasi-1D) nanofibers to investigate their electronic transport properties covering a wide temperature range from 300 down to 2 K. Since the complex structures composed of ordered conductive regions in series with disordered barriers in conducting polymer nanotubes/wires and CdS nanowires, all measured nonlinear Iâ€“V characteristics show temperature and field-dependent features and are well fitted to the extended fluctuation-induced tunneling and thermal excitation model (Kaiser expression). However, we find that there are surprisingly similar deviations emerged between the Iâ€“V data and fitting curves at the low bias voltages and low temperatures, which can be possibly ascribed to the electronâ€“electron interaction in such quasi-1D systems with inhomogeneous nanostructures.
