Abstract
Apparent mobilities of positive charge carriers in a regioregular poly(3-oc tylthiophene) film in varying oxidation states were successfully evaluated by using electrochemical techniques. Electrochemical ClO4- doping caused a decrease of the mobility by about one order of magnitude until the doping l evel reached about 2%. Further electrochemical doping resulted in the drast ic increase of the mobilities up to 0.5 cm(2) V-1 s(-1) at a maximum doping level of 23%.
