Abstract

The temperature (T), frequency (f), and electric field (E) dependent conductivity () of iodine-doped polyacetylene is reported for the concentration regime which encompasses the metal-insulator transition. No f dependence was observed for f<500 MHz. The resistance varied logarithmically with E, while lnT and exp[-(TAT)0.25] were observed. This (T,E,f) is inconsistent with simple models of metallic regions separated by large barriers and suggests that the known strong disorder plays a dominant role.
