| 3 | Enhancement of light output powers of GaN-based light emitting diodes with textured indium tin oxide transparent layer by using corrosive liquid显示文摘In order to promote the light output powers of GaN-based light emitting diodes (LEDs), two kinds of novel corrosive liquidshave been developed in this paper to roughen the surface of the indium tin oxide (ITO) current spreading layer of LEDs. As aresult, the textured transparent ITO layer greatly enhanced the external quantum efficiency of the LEDs. Provided that a wafersample was dipped in a kind of corrosive liquid developed by us for only about 60 s, the light output powers of the LEDs canbe promoted by 24.7%, compared with conventional GaN-based LEDs. It is obvious that the presented method is simple, rapidand cost-effective. | LI Yun LI XiaoChan ZHANG Tao HE AnHe HU CanDong WANG Xin HE Miao ZHANG Yong NIU QiaoLi ZHAO LingZhi LI ShuTi CHEN XianWen | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，10： | 0 |
