Abstract:
1. A radiation-emitting semiconductor component, comprising: a semiconductor body formed of a substrate and a plurality of GaN-based layers applied on said substrate; said plurality of GaN-based layers including at least one active region arranged between at least one n-conducting layer containing AlGaN and at least one p-conducting layer, and said p-conducting layer being a layer grown on in tensile-stressed form such that tensile stresses of the p-conducting layer extend in a direction substantially parallel to a plane of the layer; wherein said at least one n-conducting layer has an Al content lower than an Al content of said at least one p-conducting layer, and layers disposed between said at least one n-conducting layer and said at least one p-conducting layer are thinner than said at least one n-conducting layer so that a lattice constant thereof is defined by said at least one n-conducting layer; and wherein the Al content within said at least one n-conducting layer increases in a direction toward said substrate.
