Abstract
We have measured the temperature dependence of the conductivity of cis-polyacetylene doped with iodine and with Ir·6O. The iodine dopant was introduced from the vapor phase under various vapor pressures and also from solution. The Ir was introduced from solution. We find for and for doped with Ir. We attribute the difference to separate transport mechanisms. We suggest that the size and shape of the dopant molecule is the controlling variable rather than the doping conditions.
