Abstract

From a general band scheme appropriate for electroactive polymers, weexplain how each of the two main processes (damage or doping) inducedby ion implantation can play a major role. DC conductivity, thermopower and AC conductivity studied versus temperature for varying implantation parameters allow us to confirm our interpretations: damage is produced by high implantation parameters in which case transport phenomena of p type occur mainly in degenerate states near the Fermi level, whereas low implantation parameters induce doping in polaronic bands characterized by thermally activated processes, although effects due to the existence of defects can appear, especially at low temperature. Compensation effects, described by a Kubo-Greenwood formula applied to the thermoelectric power, give a consistent explanation of the successive behaviours. Moreover, we present a general interpretation of the p type conductivity behaviour observed in intrinsic polymers.
