Abstract

Four kinds of commercial PEDOT dispersions have been used to realize ITO/PEDOT/PF6/A1 polymeric OLEDs. The effects of the different PEDOT layers have been analyzed by using static current-voltage characterizations and dynamical admittance spectra. The measurements have revealed that the current transport is limited by the PEDOT bulk (conductivity) and not by the PEDOT work function (hole potential barrier). Moreover, admittance spectra have shown an interface state distribution having, for the tested PEDOT dispersions, similar densities but very different time constants (about 3 orders of variation). A good agreement has been found between the experimental data and the Nicollian-Brews interface states model. © 2009 IEEE.
