Abstract
The micro light-emitting diodes (
$\mu $
LEDs) offer advantages that make it an attractive option for various applications, such as displays, lighting, AR/VR, and consumer electronics. The light output power (LOP) and external quantum efficiency (EQE) of
$\mu $
LEDs are the crucial parameters that impact the performance and suitability of these devices. Ongoing studies are focused on addressing the issue of
$\mu $
LEDs. In this study, we propose several treatment strategies to modify the sidewall of
$\mu $
LEDs and improve the performance of devices. The results show that the
$\mu $
LEDs treated with citric acid (CA) and ammonium sulfide [(NH
$_{{4}}\text {)}_{{2}}$
Sx] for 1 h have the best improvement in LOP by 93.3%, and EQE increases by 91.3%. In addition, the reliability of
$\mu $
LEDs with different sidewall treatments was studied under long-term aging and high-temperature and high-humidity conditions. The treatment method for
$\mu $
LEDs has made significant contributions to the performance of devices, bringing about advancements in various key areas.
