Abstract

We present the first microwave measurements of the dynamical impedance of an individual, electrically contacted single walled carbon nanotube. Both semiconducting and metallic nanotubes are measured. Using a semiconducting nanotube, we construct an LC nano-resonator at 2 GHz. The Q of the nano-resonator can be tuned by varying the back-gate voltage on the nanotube. In contrast, the Q of a resonator fabricated with a metallic nanotube is insensitive to the back-gate voltage. This represents the first step towards passive microwave signal processing components based on carbon nanotubes.
