摘要：

We report using dielectrophoresis to accumulate hundred to thousands of solubilized single walled carbon nanotubes in parallel to achieve impedance values very close to 50 Omega. This allows us to clearly measure the real (resistive) and imaginary (inductive) impedance over a broad frequency range. We find a negligible to mild frequency dependent resistance for the devices and an imaginary impedance that is significantly smaller then the resistance over the range of dc to 20 GHz. This clearly and unambiguously demonstrates that kinetic inductance is not the major issue facing nanotube array interconnects, when compared to the real impedance (the resistance).
