Abstract
The present invention is to provide a semiconductor light-emitting element. The element comprises a substrate and a nanostructural layer. The nanostructural layer is formed on the substrate and comprises a plurality of void-embedded cortex-like nanostructures, wherein the volumetric porosity of the nanostructural layer is ranged from 30% to 59%. Compared with the prior art, the present invention can not only improve the crystalline quality of epitaxial layers but also enhance the external quantum efficiency (EQE) of the semiconductor light-emitting element.
