Abstract

In embodiments a component includes a semiconductor layer sequence having a p-side semiconductor layer, an n-side semiconductor layer and an active zone located therebetween, wherein the active zone has a multiple quantum well structure including a plurality of quantum barrier layers and quantum well layers, the quantum barrier layers and the quantum well layers being arranged alternately along a vertical direction, wherein the active zone has at least one recess having facets extending obliquely to a main surface of the active zone, the recess being opened towards the p-side semiconductor layer, wherein, at least within the recess, the quantum barrier layers are n-doped and have a non-constant doping profile so that the component is configured to increase transport negatively charged charge carriers, from the n-side semiconductor layer towards the p-side semiconductor layer, based on the non-constant doping profile, and wherein, from the n-side semiconductor layer towards the p-side semiconductor layer, dopant concentrations of the quantum barrier layers gradually increase.
