Abstract

A component having an enhanced efficiency and a method for producing a component are disclosed. In an embodiment, a component includes a semiconductor layer sequence comprising a p-conducting semiconductor layer, an n-conducting semiconductor layer and an active zone located therebetween, wherein the active zone comprises recesses on a side of the p-conducting semiconductor layer, each recess having facets extending obliquely to a main surface of the active zone, and wherein the p-conducting semiconductor layer extends into the recesses, and a barrier structure, wherein the active zone is arranged between the barrier structure and the n-conducting semiconductor layer so that an injection of positively charged charge carriers into the active zone via the main surface is hindered in a targeted manner so that an injection of positively charged charge carriers into the active zone via the facets is promoted.
