Abstract
A semiconductor body is disclosed. In an embodiment a semiconductor body includes an n-doped region comprising a first layer sequence comprising pairs of alternating layers, wherein a first layer and a second layer of each pair differ in their doping concentration, and wherein the first and second layers of each pair have the same material composition except for their doping and a second layer sequence comprising pairs of alternating layers, wherein a first layer and a second layer of each pair differ in their material composition, an active region, wherein the second layer sequence is disposed between the first layer sequence and the active region and a p-doped region, wherein the active region is disposed between the n-doped region and the p-doped region.
