Abstract
In this thesis, we demonstrate a numerical model for electrical simulation of organic light-emitting devices (OLEDs). This calculation is based on the drift-diffusion model that contains charge carrier drift with field dependent mobility, thermionic emission, heterojunction interface and recombination process. First we got the same results of the current-voltage characteristics published in literatures. Then we used our program to fit the electrical characteristics of our OLEDs, which includes conventional heterojunction (HJ) and mixing-host (MH) devices. Similar trends are obtained between the simulation and experiment results. Finally an optical simulation program was used to model the optical characteristics of HJ and MH devices which help to define the recombination zone in MH devices.
