有机电致发光器件中载流子的输运和复合发光

Transport and recombination of charge carriers in organic electroluminescent devices

以高场作用下载流子对三角势垒的Fowler Nordheim隧穿理论为基础 ,建立了单层有机电致发光器件中载流子输运和复合发光模型 ,给出了薄膜中电子 空穴对的解离和复合概率及电子和空穴的密度分布 .计算并讨论了外加电压和注入势垒对器件电流和复合效率的影响 .

Based on the Fowler-Nordheim tunneling injection,a model for carriers transport and recombination in organic single-layer devices at high electric field is presented.A complete analytic function for electron-hole pairs fission and recombination and densities of electron and hole are proposed.The influences of applied bias and injection barriers on the device current densities and light-emitting efficiencies are calculated and discussed.
