摘要
当前LED研究的重点在于提高LED的出光效率,特别是外量子效率而表面粗化是提高外量子效率最简单有效的方法之一。本文主要介绍了表面粗化提高氮化镓基LED出光效率的原理,垂直结构LED的粗化特点,并利用模拟仿真软件Tracepro对垂直结构LED的表面粗化进行了计算,确定了设定属性下出光效率最高时的条件。
At present,the focus of LED research is to improve the light efficiency of LED,especially the external quantum efficiency.Surface coarsening is one of the simplest and most effective methods to improve the external quantum efficiency.This paper mainly,introduces the principle of surface coarsening to improve the light efficiency of gallium nitride led,the coarsening characteristic of vertical structure led,and calculates the surface coarsening of vertical structure led by simulation software Tracepro,and determines the condition of the highest light efficiency under the setting conditions.
