A 10×10 deep ultraviolet light-emitting micro-LED array
文献摘要：
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 20 μm 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 emit-ting area is the same as the array.A much higher(～22％)peak external quantum efficiency,as well as a smaller efficiency droop for μ-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 each μ-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 the μ-LEDs.
