External electric field effect on electron transport in carbon nanotubes
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 conductivityComment: 5 pages, 2 figure
