In this paper, we focus on current-voltage (I-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 I-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 I-V data and fitting curves at the low bias voltages and low temperatures, which can be possibly ascribed to the electron-electron interaction in such quasi-1D systems with inhomogeneous nanostructures.
