Abstract

Charge transport in conducting polymers and single-walled carbon nanotubes is studied by means of complex dielectric spectroscopy down to 2 K. The negative dielectric constants, low plasma freqeuncies, and anomalously long relaxation times can be understood in terms of a low density of delocalized states near the Fermi level, which stems from the competition between disorder-driven localization and interchain charge transfer.
