Electric Resistance Of Carbon Nanotube With A Cu Chain: A First-Principle Calculation

Keywords

Carbon nanotube; Copper; Hybrid nanowire; Quantum mechanics; Resistance

Abstract

The electric resistance and transport properties of a carbon nanotube (5,5) adsorbed with a copper chain connected with two copper electrodes have been calculated by employing nonequilibrium Green's functions and Density Functional Theory. The properties of the pure carbon nanotube (5,5) with the Cu junction electrodes have also been calculated as a reference. Both the equilibrium and nonequilibrium conditions have been investigated. The results show that the resistance of the metallic carbon nanotube (5,5) has been reduced by the adsorption of a Cu chain due to the interaction between the Cu and the carbon nanotube. The change of the current-voltage curve slope is also explained in terms of transmission spectrum. © IMechE 2013.
