We calculate the current and electrostatic potential drop in metallic carbon nanotube wires self-consistently by solving the Green's function and electrostatics equations in the ballistic case. About one-tenth of the applied voltage drops across the bulk of a nanowire, independent of the lengths considered here. The remaining nine-tenths of the bias drops near the contacts, thereby creating a nonlinear potential drop. The scaling of the electric field at the center of the nanotube with length…

Model analysis of temperature dependence of abnormal resistivity of a multiwalled carbon nanotube interconnection.
TLDR
A homemade microwave plasma-enhanced chemical vapor deposition method was used to grow a multiwalled carbon nanotube between two nickel catalyst electrodes, and theories, such as hopping conductivity theory and variable range hopping Conductivity theory, were employed to describe resistivity in the high- and low-temperature ranges.
Electrical modelling for carbon nanotubes
Based on the NEGF and tight-binding approaches, the bias-induced energy of the metallic CNT is accounted for by the capacitance or inductance in the proposed equivalent circuit model, from which we…

Current saturation and electrical breakdown in multiwalled carbon nanotubes.
TLDR
In air failure is initiated by oxidation at a particular power, whereas in vacuum MWNTs can withstand much higher power densities and reach their full current carrying capacities, and the initiation of this failure is very sensitive to air exposure.
High-field electrical transport in single-wall carbon nanotubes
TLDR
The intrinsic high-field transport properties of metallic single-wall carbon nanotubes are measured using low-resistance electrical contacts and it is shown that the current-voltage characteristics can be explained by considering optical or zone-boundary phonon emission as the dominant scattering mechanism at high field.
Nonlinear resistance versus length in single-walled carbon nanotubes.
TLDR
A nonlinear resistance vs distance behavior as the nanotube is probed along its length is an indication of elastic electronic transport in one-dimensional systems.
