Abstract

In this paper we have reported the electrical properties of Al/ZnPc–TiO2/Al thin film device. The composite layers were prepared by the vacuum evaporation of ZnPc and sol–gel-coated TiO2. The current–voltage characteristics are found to be Ohmic and non-Ohmic at low field and high field, respectively. The charge transport conduction appears to be Poole-Frankel type of conduction. The total number of interface states, which is responsible for the dispersion of capacitance, is found to be increasing with increase in bias voltage.
