English Abstract

The research in this paper is to improve the light output power of the GaN-based light emitting diodes (LED), we try to obtain better optical and electrical properties by making the current distribution uniform. In this paper, we used several kinds of plasma on p-GaN, and try to find the optimal insulating condition by using transmission-line method (TLM). We expect to let the bottom of the p-pad region nearly insulated by using the optimal plasma treatment condition. Because the light below the p-pad will be eclipsed or reflected by the thick p-pad, this result will reduce the efficiency of output power. Therefore, we could get the higher output power by reducing the current below the p-pad region.
