Theoretical Study of Carbon Nanotubes Adsorbed on the Silicon (100) Surface, And, Explorations on the Modulation of Conductance for Metallic Carbon Nanotubes
Abstract
dc:descriptionFinally, and in a different direction, we calculate the effects of a longitudinal electrostatic perturbation on a metallic carbon nanotube to demonstrate conductance modulation. The external modulation would be screened in bulk metals but occurs in nanotubes because of their quasi two-dimensional shape allowing electrons to interact with nearby charges. This modulation is determined by the strength of the self-consistent potential and its periodicity over shorter or longer distances. We employ the zero temperature single-particle Green's function transport approach in the empirical tight-binding approximation to quantify the conductance.
