Patent abstract

An electronic device includes a conductive n-type substrate, a Group III nitride active region, an n-type Group III-nitride layer in vertical relationship to the substrate and the active layer, at least one p-type layer, and means for providing a non-rectifying conductive path between the p-type layer and the n-type layer or the substrate. The non-rectifying conduction means may include a degenerate junction structure or a patterned metal layer.
