SEMICONDUCTOR LIGHT-EMITTING ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor light-emitting element capable of stably securing high external quantum efficiency.SOLUTION: At a surface part of a substrate 10, at least one recess 20 and/or protrusion that scatters or diffracts light generated in a light-emitting region 12 is formed. The recess and/or protrusion has such a shape as not to generate a crystal defect in semiconductor layers 11 and 13.
