Study on the Effect of Dye Additives on the Charge Transport Properties of ZnO Dispersed Functional Thin Layer Film with Complex Impedance Method

Abstract

The under coated layer (UCL) in xerographic photoreceptor has various functions so as to prevent charge injection from Al substrate to charge generation layer (CGL) and to remove charge accumulation on the CGL. Metal oxide particles are commonly used as UCL, but its properties are not good enough. It is known that certain dyes are added to improve the properties of UCL. In this paper, the complex impedance spectroscopy analysis and Time-of-Flight (TOF) technique were carried out to investigate electrical charge transport behavior of metal oxide based UCL film. An effect of dye added in the film was also discussed.
