An hybrid transmission line / quantum-mechanical model is proposed for the analysis of the signal propagation along single-wall carbon nanotube. The analysis is based on the hypothesis that the electron states on the SWCN are four-fold degenerate, including spin. 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. The relevant results show that due to the quantum-mechanical effects the propagation velocity in the SWCN is much slower than in TEM waveguide. Therefore, it is demonstrated that SWCNs, a few micrometers in length, can have resonant response in the giga-hertz frequency range.

Abstract
An hybrid transmission line / quantum-mechanical model is proposed for the analysis of the signal propagation along single-wall carbon nanotube. The analysis is based on the hypothesis that the electron states on the SWCN are four-fold degenerate, including spin. 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. The relevant results show that due to the quantum-mechanical effects the propagation velocity in the SWCN is much slower than in TEM waveguide. Therefore, it is demonstrated that SWCNs, a few micrometers in length, can have resonant response in the giga-hertz frequency range.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
