In this paper, we recast the problem of interaction between a classical electromagnetic field and a pair of quantum dots coupled through dipoledipole interaction in terms of an equivalent circuit model. Then, we use the introduced circuit to investigate the electromagnetic scattering from a pair of interacting quantum dots. Equivalent circuits for complex systems of quantum dots greatly simplify the...
This paper provides a transmission line (TL) model for the propagation of electric signals along multiwall carbon nanotube (MWCNT) interconnects in the low frequency regime where interband transitions are forbidden. The electrical parameters of the TL model depend on the number of equivalent conducting channels and the intershell tunneling frequency. The tunneling current is responsible for a strong...
In carbon nanotubes (CNTs) with large radii, either metallic or semiconducting, several subbands contribute to the electrical conduction, while in metallic nonarmchair nanotubes with small radii the wall curvature induces a large energy gap. In this paper, we propose a model for the signal propagation along single wall CNTs (SWCNTs) of arbitrary chirality, at microwave through terahertz frequencies,...
The paper presents a self-consistent semi-classical model describing the electrical behavior of carbon nanotube interconnects. The model deals with the general case of arbitrary chirality and takes rigorously into account the effects of nanotube size and chirality on its electrical parameters. The general model includes as particular cases the models currently used in literature to describe metallic...
