Extraction of nanoelectronic parameters from quantum conductance in a carbon nanotube

A newfangled paradigm through the deployment of the quantum conductance and non-equilibrium Arora's distribution function (NEADF) is shown to be in compliance with the experimental nonlinear I-V characteristics defying ohmic and ballistic conduction in a carbon nanotube (CNT). Resistance quantum is a result of scaled-down channel below the scattering limited mean free path (mfp). The critical electric field equal to the thermal/Fermi voltage divided by mfp is at the essence of nonlinear current-voltage characteristics, making signal resistance distinct from the direct one, bringing to focus the exponential signal resistance surge with the applied voltage across a CNT channel.
