Abstract
A light emitting diode (LED) is provided along with a method of making the same. The LED includes a conductive n-type region formed on a substrate; an active region formed on the n-type region; a first p-type region formed on the active region; a plurality of nanostructures formed on the first p-type region to carry out light extraction from the active region, the nanostructures having a diameter less than 500 nm; a second p-type region regrown on the first p-type region to form a non-planar surface in combination with the nanostructures; and a p-type electrode formed on the non-planar surface.
