OPTOELECTRONIC SEMICONDUCTOR BODY WITH A TUNNEL JUNCTION AND METHOD FOR PRODUCING SUCH A SEMICONDUCTOR BODY

摘要

An optoelectronic semiconductor body includes an epitaxial semiconductor layer sequence including a tunnel junction including an intermediate layer between an n-type tunnel junction layer and a p-type tunnel junction layer, wherein the intermediate layer has an n-barrier layer facing the n-type tunnel junction layer, a p-barrier layer facing the p-type tunnel junction layer, and a middle layer with a material composition differing from material compositions of the n-barrier layer and the p-barrier layer; and an active layer that emits electromagnetic radiation.
