摘要
Surface morphologies of the metal-organic chemical vapor deposition-grown p-GaN layers with and without Si treatment were investigated by atomic force microscope and scanning electron microscope. It was found that Si treatment resulted in a much rougher sample surface due to the formation of a thin SixNy layer. It was also found that forward voltage of the Si-treated InGaN-GaN light-emitting diode (LED) was slightly higher than that of conventional LED without Si treatment. However, it was also found that such Si treatment could also result in a much larger LED output intensity.
