Extraction of nanoelectronic parameters from quantum conductance in a carbon nanotube

A newfangled paradigm through the deployment of the quantum conductance and nonequilibrium 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.
