Modelling of multiwall carbon nanotube transmission lines

A hybrid transmission line/quantum-mechanical model is proposed for the analysis of multiwall carbon nanotubes in the radio frequency range. The developed model applies to multiwall carbon nanotubes having high number of shells, and diameter ranging from about 50 nm to 150 nm, like the ones growing inside alumina membranes. Numerical calculations are performed in order to assess the influence of the p.u.l. kinetic inductance and of the p.u.l. quantum capacitance on the propagation characteristics.
