LIGHT EMITTING ELEMENT AND MANUFACTURING METHOD THEREOF

摘要

A light emitting element includes a substrate, a GaN layer formed on the substrate, a first low refractive index semiconductor layer formed on the GaN layer, and a lighting structure having a high refractive index formed on the first low refractive index semiconductor layer. A second low refractive index semiconductor layer is embedded in the first low refractive index semiconductor layer. The first low refractive index semiconductor layer and the GaN layer exhibit a lattice mismatch therebetween.
