摘要: An optoelectronic semiconductor chip is disclosed. In an embodiment the chip includes an active zone with a multi-quantum-well structure, wherein the multi-quantum-well structure comprises multiple quantum-well layers and multiple barrier layers, which are arranged sequentially in an alternating manner along a growth direction, wherein the multi-quantum-well structure has at least one emission region and multiple transport regions which are arranged sequentially in an alternating manner in a direction perpendicular to the growth direction, wherein at least one of the quantum-well layers and the barrier layers are thinner in the transport regions than in the emission regions, and wherein the quantum-well layers in the transport regions and in the emission regions are oriented perpendicularly to the growth direction with exception of a junction region between adjacent transport regions and emission regions.

摘要: The invention relates to a component (10) having a semiconductor layer sequence, which has a p-conducting semiconductor layer (1), an n-conducting semiconductor layer (2), and an active zone (3) arranged between the p-conducting semiconductor layer and the n-conducting semiconductor layer, wherein the active zone has a multiple quantum well structure, which, from the p-conducting semiconductor layer to the n-conducting semiconductor layer, has a plurality of p-side barrier layers (32p) having intermediate quantum well layers (31) and a plurality of n-side barrier layers (32n) having intermediate quantum layers (31). Recesses (4) having flanks are formed in the semiconductor layer sequence on the part of the p-conducting semiconductor layer, wherein the quantum well layers and/or the n- and p-side barrier layers extend in a manner conforming to the flanks of the recesses at least in regions. The interior barrier layers have a larger average layer thickness than the p-side barrier layers.
