Description
Summary:Electrical properties of Schottky barrier diode fabricated using Aluminum for Schottky contact and indium tin oxide for ohmic contact and containing polypyrrole doped with dodecylbenzene sulfonic acid in the presence and in the absence of a plasticizing agent hydroquinone were studied. Various parameters, e.g. saturation current, ideality factor, built in voltage; carrier concentration and barrier height have been calculated and found to be affected by the presence of hydroquinone in the doped polymer. The electrical behavior of the systems was found to be in a good agreement with the thermionic emission model for the Schottky barrier devices. The interaction of the doped polypyrrole with hydroquinone was explained in terms of change in the barrier height and in the carrier concentration of the diodes.
