    Abstract

    Theoretical equations for current-voltage characteristics in mono-layer unipolar devices and multilayer bipolar device (that is, OLED) are investigated on the basis of the model consisting of diffusion theory of internal carrier emission through Schottky barrier at cathode and anode electrodes and electronic field dependence of carrier mobility, so called Pool-Frenkel mobility. Space charge effects are also included in this model, which is not presented as a simple Mott-Gurney law. The current-voltage characteristics of OLED are presented using a behavioral language for analog systems (Verilog-A), and the accuracy of this model was verified by comparing with the device simulation results.
