Electrode specific electropolymerization of ethylenedioxythiophene: Injection enhancement in organic transistors
Abstract
In this letter, we report on a method of decreasing the injection barrier from metal electrodes to organic semiconductors, namely pentacene and poly(triarylamine) (PTAA). This method involves the electrodeposition of PEDOTPSS on to the source electrode of an organic field-effect transistor (OFET) without unintended doping of the channel. In an OFET, the drain current injected at the PEDOTPSS coated gold electrode increases (2-6) fold over that of the current injected at the unmodified gold electrode, all else being the same. Furthermore, in the transistor with a polytriarylamine as the semiconductor, a decrease of the threshold voltage is observed. © 2005 American Institute of Physics.
