Semiconductor layer sequence, an optoelectronic semiconductor chip and a process for the preparation of a semiconductor layer sequence

摘要

In at least one embodiment, the semiconductor layer sequence (1) for an optoelectronic semiconductor chip (10) is provided. The semiconductor layer sequence (1) contains at least three quantum wells (2), which, in order to create an electromagnetic radiation are set up. Furthermore, the semiconductor layer sequence (1) a plurality of barrier layers (3), of which in each case at least one between two adjacent quantum wells (2) is arranged. The quantum wells (2) have a first middle indium content and the barrier layers (3) a second, smaller average indium content on. A second average grating constant of the barrier layers (3) is smaller than a first average grating constant of the quantum wells (2).
