Abstract:
1. A GaN based Light Emitting Diode (LED) comprising: a substrate; a light emitting structure formed on said substrate including an active region; a multi-layer window structure formed of a first layer and a second layer of Mg doped GaN, said window structure being disposed on the light emitting structure; a transparent conductive outer layer formed on the window structure, the conductive outer layer having an exposed surface and at least one opening formed therein; a first opening in said transparent conductive outer layer, exposing an upper surface of a portion of the Mg doped GaN multi-layer window structure; a second opening formed through to the N cladding layer of the light emitting structure at one side of said light emitting structure; and a complementary pair of electrodes defined by:
