AbstractMicro-structured InGaN light-emitting diodes (μLED) are capable of delivering enhanced light output due to additional light extraction through exposed sidewalls. However, these sidewalls formed by plasma etching can potentially affect the lifetime and reliability of the devices as a result of plama damage. A study on the electrical characteristics and reliability of μLED arrays has been carried out in this work. Although improved optical performance can be expected based on previous studies, expanded device sidewalls prove to accelerate the rate of optical degradation, adversely affect the lifetimes of devices. Through precise current-voltage measurement vertical current conduction along the plasma-damaged sidewalls was identified as the key mechanism contributing to degraded reliability. © 2011 WILEY-VCH Verlag GmbH & Co.
