Abstract
The metallic state in conjugated polymers and single-walled carbon nanotubes is studied by dielectric spectroscopy (8–600 GHz). We have found an intriguing correlation between scattering time and plasma frequency This relation conflicts with the usually applied models that only consider disorder. Based on the observed parallels with doped semiconductors, we argue that the interchain coupling plays a role comparable to the doping level and that the unusual free-carrier dynamics in the metallic state can be explained when including the role of in the conventional models.
