摘要:

研究了不同厚度的多量子势垒电子阻挡层(MQB-EBLs)对InGaN UV LED的效率的影响。分析了影响不同厚度MQB-EBLs的LED光输出功率(LOP)的主要因素。实验表明,MQB-EBLs的量子阱层和势垒层厚度为分别为2 nm和3 nm时,387 nm UV LED的LOP可显著地提升到8.47 mW。

关键词: 多量子阱电子阻挡层, UV LED, 光输出功率

Abstract:

The influence of the thickness of the multi-quantum barrier electron blocking layer (MQB-EBLs) on the efficiency of InGaN-based ultraviolet (UV) light-emitting diode (LED) is discussed.The dominant factors of the effect of thickness of MQB-EBLs on the efficiency of InGaN-based UV LED are investigated.The results show that the light output power (LOP) of 387 nm UV LED can attain 8.47 mW when the thickness of quantum well and barrier of the MQB-EBLs are 2 nm and 3 nm,respectively.

Key words: MQB EBLs;UV LED;LOP
