Abstract
An optoelectronic component and a method for the producing an optoelectronic component are disclosed. In an embodiment, the component comprises an active zone for generating electromagnetic radiation, wherein the active zone adjoins at least one layer arrangement of a semiconductor material, wherein the layer arrangement comprises at least two layers, wherein the two layers are formed in such a way that at an interface between the two layers a piezoelectric field is provided, the piezoelectric field configured to provide an electrical voltage drop at the interface, wherein a peak doping region is provided at the interface of the two layers in order to reduce the electrical voltage drop, wherein, in the direction away from the active zone, a doping of the peak doping region increases at least by a first percentage value and then decreases by at least a second percentage value, and wherein the first percentage value and the second percentage value are greater than 10% of a maximum doping of the peak doping region.
