SUBMICRO-FACET LIGHT-EMITTING DEVICE AND METHOD FOR FABRICATING THE SAME

摘要

A light emitting device comprises an n-type layer, a p-type layer, and an active region sandwiched between the n-type layer and the p-type layer, wherein the active-region has a wavy structure with nano or micro fluctuations in its thickness direction. The n-type layer comprises crystal facets on its upper surface, and the active-region is conformally formed on the upper surface of the n-type layer and substantially follows the shape of the crystal facets so as to form the wavy structure. A method for fabricating the same is also provided.

1. A light emitting device comprising:
a substrate; an n-type layer formed over the substrate; a p-type layer; an active region sandwiched between the n-type layer and the p-type layer; wherein the active-region is a continuous layer over substantially an entire upper surface of the substrate and has a wavy structure with nano or micro fluctuations in its thickness direction.
