摘要:

In this paper, silicon oxynitride is deposited through plasma-enhanced chemical vapor deposition (PECVD) to serve as an antireflection passivation layer. We have studied the effects of the deposition temperature (from 100 to 300 degrees C) on the electrical and optical performances of GaN-LEDs. It is found that the light output of GaN-LEDs improves greatly after the deposition of SiON antireflection passivation layer at 200 degrees C and is better than that of GaN-LEDs whose layers are deposited at 100 and 300 degrees C. The electrical properties of GaN-LED do not degrade at 100 and 200 degrees C, but degrade significantly at 300 degrees C. (C) 2007 Elsevier B.V. All rights reserved.
