Abstract
, attributed to increased radiative recombination. Furthermore, results suggest improved efficiency retention at higher injection levels, pointing to reduced current roll-off limitations and extended high-brightness operation. Additionally, PR plays a crucial role in mitigating optical losses and improving outcoupling efficiency, especially in plasmonic-enhanced systems, where scattering effects increase the prevalence of trapping states. These findings open up exciting possibilities for devices requiring energy-efficient, compact, and high-performance light sources, such as portable electronics and low-power displays.
