Effects of Surface Texture on the Light Emission of Red LEDs

Abstract
This paper will discuss the influence of the surface texture on the optical properties of LEDs by using the Monte Carlo method to simulate two dimensional red LEDs.The surface texture,which has a 4μm etching depth,2μm etching width,40 degree obliquity,and 2μm cycle,is formed by chemical etching.The experimental result indicates that the light-intensity increased by 20.56%.After analyzing the result of this simulation and experiment,we conclude that this method of introducing the surface texture has an effective impact on the light-intensity of LEDs-
