This study presents an optimized design of green-emitting Micro-LED structures, using numerical simulations to elucidate the pivotal role of the Micro-LEDs with the pre-well and pre-layer configuration in alleviating polarization-related electric fields and promoting energy band flattening. The simulation quantitatively demonstrates the structure's effectiveness in enhancing wave function overlap and radiative recombination efficiency. These insights provide a robust theoretical foundation for the experimentally observed enhancements in external quantum efficiency, wavelength stability, and high-speed modulation performance of the optimized devices.

The operation of a p-n junction diode involves various biasing conditions, including forward bias, reverse bias, and equilibrium.
In equilibrium, no external voltage is applied across the p-n junction. The depletion region is formed at the junction interface due to the diffusion of carriers, which leaves behind charged dopants, acceptors on the p-side, and donors on the n-side. These immobile charges create an electric field that prevents further diffusion of carriers. The related energy band...

497
Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...
