Electrical Transport Properties of Polyacetylene and Related Compounds

A survey is given on electrical transport phenomena in polyacetylene. Data on the dependence of the conductivity on temperature frequency and doping concentration are reviewed and measurements of the magnetoresistance and of long-time aging effects under various storage conditions are presented. The experimental results are interpreted as superposition of intra- chain, inter-chain and inter-fiber conduction mechanisms, and resemble some aspects of the hopping transport in disordered semiconductors.
