The determination of the conduction mechanism and extraction of diode parameters of ITO/PEDOT-PSS/POLYMER/Al heterojunction diode

ITO/PEDOT-PSS/POLYMER/Al heterojunction diode was fabricated. The current-voltage characteristics have been studied to explain of rectification generation and the luminance-voltage (L-V) characteristics of the diode have also been investigated. The diode shows non-ideal I-V behavior with an ideality factor greater than unity. The conduction mechanism was determined and a Schottky type conduction process was defined. The diode parameters such as barrier height and ideality factor were found as 0.71 eV and 2.07, respectively.
