Conduction in Polyacetylene Nanofibers at Low Temperatures
The current‐voltage (I‐V) characteristics of individual nanofibers of lightly‐doped polyacetylene show very strong nonlinearities. At low temperatures the I‐V characteristics are consistent with Zener‐type tunneling, and independent of temperature and magnetic field. These features suggest a novel conduction mechanism that involves tunneling of a segment of the conjugated bond system in the presence of an electric field, creating a pair of charged solitons.
