The I-V characteristics of iodine doped polyacetylene (PA) nanofibers were measured as function of temperature. Platinum electrodes on top of SiO2 substrates were used to prevent reaction with iodine dopant. The distance between the two electrodes is approximately 100 nm. Upon iodine doping, non-ohmic I-V characteristics are observed. The gate dependence shows the charge carrier to be hole with a mobility μFET ∼ 4.4×10-5 cm2/Vs at 233K.
