Modeling the propagation of electrical signals along carbon-based nano-interconnects

This paper provides a transmission line (TL) model for the propagation of electric signals along graphene nanoribbon and carbon nanotubes interconnects in the sub-terahertz frequency range. The electrical parameters are written in terms of classical terms and quantum ones. The peculiar behavior of these parameters as a function of the transverse size and of the temperature is investigated, as well as the dispersion relation of the propagation velocity.
