Abstract: The invention relates to a method for producing a radiation-emitting semiconductor body, including the following steps: providing a growth substrate having a main surface; producing a plurality of distributor structures on the main surface of the growth substrate; epitaxially depositing a compound semiconductor material on the main surface of the growth substrate, wherein the epitaxial growth of the compound semiconductor material varies along the main surface because of the distributor structures, such that the epitaxial deposition produces an epitaxial semiconductor layer sequence having at least a first emitter region and a second emitter region on the main surface, the first emitter region and the second emitter region being laterally adjacent to each other in a top view of a main surface of the semiconductor body, and the first emitter region and the second emitter region producing electromagnetic radiation of different wavelength ranges during operation. The invention also relates to a radiation-emitting semiconductor body.

Abstract: The invention relates to a component with a main part and a contact structure. The main part has an active zone which is designed to generate electromagnetic radiation at least in some regions during the operation of the component. The contact structure has a plurality of individually actuatable segments. The component has a connection surface and a lateral surface running transversely to the connection surface, and the lateral surface is designed as a radiation passage surface of the component. The connection surface is designed to be structured, wherein the connection surface is defined by common internal boundary surfaces between the main part and the contact structure, and each segment has a local common boundary surface with the main part and is designed for a pixelated current impression into the main part. The invention additionally relates to a method for operating such a component.
