Abstract

Electronic conduction in conjugated polymers is of emerging technological interest for high-performance optoelectronic and thermoelectric devices. A completely new aspect and understanding of the conduction mechanism on conducting polymers is introduced, allowing the applicability of materials to be optimized. The charge-transport mechanism is explained by direct experimental evidence with a very well supported theoretical model.

Keywords: chemical vapor deposition; conducting polymers; poly(3,4-ethylenedioxythiophene) (PEDOT).
