Abstract
A radiation-emitting semiconductor body having a semiconductor layer sequence includes an active region that generates radiation, an n-conducting region and a p-conducting region, wherein the active region is located between the n-conducting region and the p-conducting region, the p-conducting region includes a current expansion layer based on a phosphide compound semiconductor material, and the current expansion layer is doped with a first dopant incorporated at phosphorus lattice sites.
