| 1 | A 10×10 deep ultraviolet light-emitting micro-LED array显示文摘In this work,we design and fabricate a deep ultraviolet(DUV)light-emitting array consisting of 10×10 micro-LEDs(μ-LEDs)with each device having 20μm in diameter.Strikingly,the array demonstrates a significant enhancement of total light output power by nearly 52%at the injection current of 100 mA,in comparison to a conventional large LED chip whose emitting area is the same as the array.A much higher(~22%)peak external quantum efficiency,as well as a smaller efficiency droop forμ-LED array,was also achieved.The numerical calculation reveals that the performance boost can be attributed to the higher light extraction efficiency at the edge of eachμ-LED.Additionally,the far-field pattern measurement shows that theμ-LED array possesses a better forward directionality of emission.These findings shed light on the enhancement of the DUV LEDs performance and provide new insights in controlling the light behavior of theμ-LEDs. | Huabin Yu Muhammad Hunain Memon Hongfeng Jia Haochen Zhang Meng Tian Shi Fang Danhao Wang Yang Kang Shudan Xiao Shibing Long Haiding Sun | 2022 | Journal of Semiconductors2022，43，6： | 3 |
| 2 | Cascaded deep ultraviolet light-emitting diode via tunnel junction显示文摘The Al Ga N-based deep ultraviolet(DUV)light-emitting diode(LED)is an alternative DUV light source to replace traditional mercury-based lamps.However,the state-of-the-art DUV LEDs currently exhibit poor wall-plug efficiency and low light output power,which seriously hinder their commercialization.In this work,we design and report a tunnel-junctioncascaded(TJC)DUV LED,which enables multiple radiative recombinations within the active regions.Therefore,the light output power of the TJC-DUV LEDs is more than doubled compared to the conventional DUV LED.Correspondingly,the wall-plug efficiency of the TJC-DUV LED is also significantly boosted by 25%at 60 m A. | 余华斌 任钟杰 Muhammad Hunain Memon 方师 汪丹浩 刘钟灵 张昊宸 吴峰 戴江南 陈长清 孙海定 | 2021 | Chinese Optics Letters2021，19，8： | 3 |
