The mechanism of electrical conductivity as a function of temperature is consistent with a hopping type carrier transport. The electrical conductivity decreased, as a function of time, in agreement with a granular metal type structure, in which aging is due to the shrinking of the PEDOT conductive grains. XPS and UPS spectra indicate that conformational changes of the PEDOT:PSS film are responsible for this behaviour and a model for these modifications is proposed.||URI:||http://ktisis.cut.ac.cy/handle/10488/837||ISSN:||1566-1199||DOI:||10.1016/j.orgel.2008.10.008||Rights:||Copyright © 2008 Elsevier B.V.
