Abstract

The temperature dependences of the conductivity, the magnetic susceptibility and the thermoelectric power of iodine-doped highly conducting (ca. 105 S/cm) polyacetylene are presented. The conductivity shows non-activated behavior down to mK region. The density of states derived from the susceptibility and the thermoelectric power is consistent with one-electron band calculation. The electron localization due to the quasi one-dimensionality inherent to polymer is considered to beviolated by mesoscopic potential disorder, resulting in metallic strands, which are connected by tunneling.
