Abstract:
In various embodiments, light-emitting devices incorporate graded layers with compositional offsets at one or both end points of the graded layer to promote formation of two-dimensional carrier gases and polarization doping, thereby enhancing device performance.

Claim (Index 26):
A semiconductor device comprising:\n a substrate; an Al v Ga 1-v N layer disposed over the substrate; a graded Al z Ga 1-z N layer disposed over the Al v Ga 1-v N layer, a composition of the graded Al z Ga 1-z N layer being graded in Al concentration z from a bottom portion to a top portion, such that the Al concentration z decreases from the bottom portion, in a direction away from the Al v Ga 1-v N layer, to the top portion; an Al w Ga 1-w N cap layer disposed over the graded Al z Ga 1-z N layer; and a metallic contact disposed over the Al w Ga 1-w N cap layer and comprising at least one metal, wherein the Al concentration z of the bottom portion of the graded Al z Ga 1-z N layer is less than an Al concentration v of the Al v Ga 1-v N layer.
