Abstract
A quantum well structure according to the invention includes a quantum well layer () arranged between two barrier layers (). It is distinguished in that at least one of the barrier layers () includes nanostructures () which compensate or modulate a lateral homogeneity of the barrier layer (), that exists without the nanostructures (), that is to say a homogeneity in the directions extending perpendicularly to the stacking direction of the layers in the quantum well structure.
