Abstract

We have studied the internal space charge behavior of a new functional organic insulators such as organic photoconductor (OPC) and organic light emitting diode (OLED). In this paper, some results of the experiments are reported for the specimens which are charge transport layer (CTL) of the OPC and light emitting layer (Alq3) of the OLED with the different kinds of the electrode materials. The experimental results indicate that the electron/hole injection into the new functional organic layer from the electrodes are influenced by the Fermi level of the electrode material. We will discuss the electronic behavior of the localized energy states of the new functional organic layer based on the measurement of the internal phenomena
