Abstract
A nano-structured light-emitting device (LED) includes: a plurality of nanostructures on a first type semiconductor layer. Each of the plurality of nanostructures includes: a first type semiconductor nanocore on a portion of the first type semiconductor layer; a current spreading layer formed to cover a surface of the first type semiconductor nanocore and formed of an AlGaN(0<x<1)/GaN superlattice structure; an active layer on the current spreading layer (or on the first type semiconductor nanocore if the current spreading layer is embedded in the first type semiconductor nanocore); and a second type semiconductor layer on the active layer.
