Abstract
Results of coordinated measurements of DC and microwave conductivity of polyacetylene doped with iodine to moderate levels are presented and discussed within a hopping model using the extended pair approximation. At low temperatures the DC data follow Mott'sT −1/4 law indicating similarities between polyacetylene and amorphous semiconductors. A detailed analysis gives a qualitative description of the evolution of the density of states near the Fermi energy upon doping.
