Abstract:
The invention relates to an optoelectronic semiconductor element (100) comprising a semiconductor layer sequence (1) with a first layer (10) of a first conductivity type, a second layer (12) of a second conductivity type, and an active layer (11) which is arranged between the first layer (10) and the second layer (12) and which absorbs or emits electromagnetic radiation when operated as intended. The semiconductor element (100) is equipped with a plurality of injection regions (2) which are arranged adjacently to one another in a lateral direction, wherein the semiconductor layer sequence (1) is doped within each injection region (2) such that the semiconductor layer sequence (1) has the same conductivity type as the first layer (10) within the entire injection region (2). Each injection region (2) passes at least partly through the active layer (11) starting from the first layer (10). Furthermore, each injection region (2) is laterally surrounded by a continuous path of the active layer (11), the active layer (11) being doped less in the path than in the injection region (2) or oppositely thereto. During the operation of the semiconductor element (100), charge carriers reach the injection regions (2) at least partly from the first layer (10) and are directly injected into the active layer (11) from there.
