Abstract
An optoelectronic semiconductor body includes a semiconductor layer sequence having an active region that generates radiation, a first barrier region and a second barrier region, wherein the active region is arranged between the first barrier region and the second barrier region; and at least one charge carrier barrier layer is arranged in the first barrier region, said at least one charge carrier barrier layer being tensile-strained.
