Abstract
The electrical conductivity of a bulky polythiophene or a bulky gold has high value. If the electrical conductivity of nanometer scale films of polythiophene or gold has high value, it is very interesting that the molecular devices are combined with these polythiophene. The Langmuir-Blodgett (LB) films were synthesized from poly(3-hexylthiophene) (P3HT), and the LB films of P3HT were doped by the electrochemical method in present study. Samples of Al/P3HT LB films/Au generated the voltage. The time dependence of the voltage generated from the Al/P3HT LB films/Au was measured. The electrochemical doping caused the generated voltage of the samples to increase.
