Non-ohmic behaviors under high electric field were investigated for highly conducting iodine-doped polyacetylene at different temperatures. The field dependence was enhanced with decrease of measuring temperature and conductivity. Through systematic numerical analysis we show that the high-field characteristics at different temperatures cannot be described consistently by Sheng model which has been utilized for analyzing the temperature dependence of conventional polyacetylene.
