Abstract

In this letter, the radio-frequency (RF) transmission properties of single-walled carbon nanotubes (CNTs) have been characterized up to the frequency of 12 GHz in a carbon nanotube field-effect transistor (CNFET) configuration using a two-port S-parameter method for the first time. The RF characteristics of the CNTs were measured from the drain to the source of the CNFET. A resistance, inductance, and capacitance model has been proposed, and the element values have been extracted. Without the effect of the parasitics, the RF signal transmission in the CNTs presents no degeneration even at 12 GHz. The capacitive contact between CNTs and metal electrodes is reported.
