Abstract:
1. An optoelectronic semiconductor chip comprising the following sequence of regions in a growth direction of the optoelectronic semiconductor chip: a p-doped barrier layer for an active region; said active region, which is suitable for generating electromagnetic radiation, said active region being based on a hexagonal compound semiconductor; an n-doped barrier layer for said active region, wherein said active region comprises a quantum well structure for generating at least a part of said electromagnetic radiation, and at least one further quantum well structure which is not provided for generating radiation and which is disposed below said quantum well structure provided for generating radiation, as seen in the growth direction, wherein said at least one further quantum well structure which is not provided for generating radiation is exclusively arranged between said p-doped barrier layer and said quantum well structure for generating said at least a part of said electromagnetic radiation, and wherein said at least one further quantum well structure which is not provided for generating radiation is a diffusion barrier for a p-dopant from said p-doped barrier layer.
