Abstract: A semiconductor structure comprises an n-doped first layer, a p-doped second layer doped with a first dopant, and an active layer disposed between the n-doped first layer and the p-doped second layer and having at least one quantum well. The active layer of the semiconductor structure is divided into a plurality of first optically active regions, at least one second region, and at least one third region. Here, the plurality of first optically active regions are arranged in a hexagonal pattern spaced apart from each other. The at least one quantum well in the active region comprises a larger band gap in the at least one second region than in the plurality of first optically active regions and the at least one third region, the band gap being modified, in particular, by quantum well intermixing. The at least one second region encloses the plurality of first optically active regions.

Abstract: An optoelectronic semiconductor device may include a first and second semiconductor layer having a first and second conductivity type, respectively, a first contact structure, a contact layer, and a separating layer. Contact holes are arranged in the separating layer. The optoelectronic semiconductor device may include portions of a conductive layer arranged over a side of the separating layer facing away from the contact layer. The portions of the conductive layer are each connected to a conducting material in the contact holes. The first contact structure is connected to the contact layer via the portions of the conductive layer and the conducting material. A length of each of the portions is greater than a greatest width of the portions. The length denotes a shortest distance between an associated contact hole and a conductive material between adjacent portions, and the width is measured perpendicular to the length.
