Radio-frequency characterization for the single-walled carbon nanotubes

Carbon nanotube (CNT) has a potential to be used as nanoscale transmission lines and as high-performance passive components in nanoelectronics. In this letter, we discuss single-walled carbon nanotubes (SWNTs) that were grown using a chemical-vapor deposition technique. Both the dc and ac two-terminal resistances were measured and analyzed. The transmission properties of the SWNTs were shown by comparing the S parameters of a device with CNTs with those of a device without a CNT. The radio-frequency characterization of the CNTs was carried out using the network analyzer to frequency of 20 GHz. (c) 2006 American Institute of Physics.
