Abstract

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.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
