Abstract
An optoelectronic device includes a carrier on which a semiconductor layer sequence is applied, said semiconductor layer sequence including an n-doped semiconductor layer and a p-doped semiconductor layer such that a p-n junction is formed which includes an active zone that generates electromagnetic radiation, wherein at least one of the n-doped semiconductor layer and the p-doped semiconductor layer includes a doped region having a first doping concentration greater than a second doping concentration in a surrounding area of the region in the semiconductor layer including the region.
