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
