摘要

对发光二极管(LED)顶部金属电极网状设计引起的非均匀注入电流进行了数值研究。用有限元法求解了三维电势拉普拉斯方程。该数值模型结合了映射的无限元来考虑远离LED结构的潜在衰减，并针对网格开口中半导体-空气界面的边界条件建立了有限元模型。仿真结果验证了网格几何参数对总输出功率的影响。

Modeling of light-emitting diode with nonuniform current injection

Light-emitting diode (LED) with nonuniform current injection caused by the mesh-like design of top metal electrode is studied numerically. Three-dimensional Laplace equation for electric potential is solved by finite element method. The numerical model incorporates mapped infinite element to account for potential decay far away from the LED structure and finite element model developed for boundary condition at semiconductor-air interface in the mesh opening. Simulation results demonstrate the effect of the mesh geometrical parameters on the total output power.
