摘要
advantages for display, visible-light communication (VLC), and other novel applications. The smaller size of LEDs affords them the benefits of enhanced current expansion, fewer self-heating effects, and higher current density bearing capacity. Low external quantum efficiency (EQE) resulting from non-radiative recombination and quantum confined stark effect (QCSE) is a serious barrier for application of mu LEDs. In this work, the reasons for the poor EQE of mu LEDs are reviewed, as are the optimization techniques for improving the EQE of mu LEDs.
