Abstract :
We study electrical conduction in carbon nanofibers from 0.1 to 30 GHz, by measuring the S-parameters of a ground-signal-ground test structure in which a nanofiber forms part of the signal path. If the nanofiber is modeled as a resistor, the S-parameters are reproduced well by a simple, but realistic, lumped RC circuit model. This implies that, as at low frequencies, nanofibers behave as resistors all the way up to microwave frequencies.
