Enhanced external quantum efficiencies of AlGaN-based deep-UV LEDs using reflective passivation layer

In this study, deep ultraviolet light-emitting diodes (DUV-LEDs) with a reflective passivation layer (RPL) were investigated. The RPL consists of HfO 2 /SiO 2 stacks as distributed Bragg reflectors, which are deposited on two DUV-LEDs with different p -GaN thicknesses. The RPL structure improved the...
