FEM Simulation on the Charge Transport and Exciton Dynamics in OLED Devices

초록

In this paper, we report on our finite element method (FEM) study on the charge transport and exciton dynamics for Alq3-based organic light emitting diode (OLED). We investigated the carrier transport and recombination mechanism of the two-layer structure and thereby devised a high-efficiency device structure. This paper also reports the effect of the insertion of the emission layer (EML) and also the dependence of the efficiency on the internal barrier height.
