Vertical gallium-nitride based light emitting diode

摘要

A vertical GaN-based LED is provided. The vertical GaN-based LED includes: an n-electrode; an n-type GaN layer formed under the n-electrode; an active layer formed under the n-type GaN layer; a p-type GaN layer formed under the active layer, the p-type GaN layer having a first uneven structure formed on a surface that does not contact the active layer; a p-type reflective electrode formed under the p-type GaN layer having the first uneven structure; and a support layer formed under the p-type reflective electrode.
