Abstract
Electronic transport properties of carbon nanotubes are studied theoretically in the presence of external electric field E(t) by using the Boltzmann's transport with constant relaxation time. An analytical expression for the current densities of the nanotubes are obtained. It is observed that the current density-electric field characteristics of the CNs exhibit total self-induced transparency and absolute negative conductivity
Highlights
The electrical transport properties of carbon nanotubes (CNs) have been the subject of much research ever since the discovery by Iijima [1] of the quasi-one-dimensional monomolecular structures
In this paper we study theoretically two phenomena in CNs, which are self-induced transparency and absolute negative conductance for the following cases respectively: 1) When the CNs is exposed to an a. c. electric field i.e
Using the solution to the Boltzmanns transport equation with constant relaxation time, we report on a theoretical analysis of a simple model of carbon nanotubes (CNTs) subject to an external electric field
Summary
The electrical transport properties of carbon nanotubes (CNs) have been the subject of much research ever since the discovery by Iijima [1] of the quasi-one-dimensional monomolecular structures. This may be due to their abilities to exhibit Bloch oscillations [2,3,4,5] at moderate electric field strengths. This oscillatory response makes CNs inherently nonlinear and as such can perform varieties of transport phenomena. 2) When the CNs is exposed to an a. c. and d.c electric field i.e. E (t=) Eo + E1 cosωt
