Therefore, it is important to develop a useful simulation tool assisting in the device design of the organic materials. In the past, 1D Poisson and drift-diffusion solver have been developed by considering Gaussian-shaped density of state and Poole-Frenkel model to simulate organic materials. In this thesis, we study the method about setting up the distribution of density of state by considering the absorption spectrum of the material. The result shows that is a more appropriate method in modeling the density of state in organic materials. Moreover, 2D random dopant model is hence developed to treat the effect of random doping distribution in low doping conditions. We further calculate the 2D exciton distribution and the internal quantum efficiency (IQE) by 2D finite element method. The results show that it is consistent with experimental data.2676810 bytesapplication/pdf論文公開時間: 2016/8/25論文使用權限: 同意有償授權(權利金給回饋學校)有機發光二極體能態密度場依存性載子遷移率隨機參雜激子擴散organic light emitting diodesdensity of statesfield-dependent mobilityrandom dopingexciton diffusionthesis10.6342/NTU201602865http://ntur.lib.ntu.edu.tw/bitstream/246246/273027/1/ntu-105-R03941009-1.pdf
