Abstract:
1. An optoelectronic semiconductor chip, based on a nitride material system, comprising: at least one active quantum well; wherein during operation electromagnetic radiation is generated in the at least one active quantum well; wherein the active quantum well comprises N successive zones (A) in a direction parallel to a growth direction z of the optoelectronic semiconductor chip, N being a natural number; wherein at least two of the successive zones (A) have average indium contents c which differ from one another; wherein the at least one active quantum well fullfils the following condition: wherein N is greater than or equal to 4 and in which, in the direction parallel to the growth direction z and from a p-connection side (p) towards an n-connection side (n) of the optoelectronic semiconductor chip, the following relationships apply for an average indium content c for at least some of the successive zones (A): wherein the successive zones (A) are numbered consecutively in a direction parallel to the growth direction z; wherein a total thickness of the active quantum well is between 3.5 nm and 8 nm, inclusive; wherein a thickness of each zone of the successive zones is between 1.5 nm and 3 nm, inclusive; and wherein the indium content of at least one zone, which is adjacent to a zone with a maximum indium content, is between 40% and 60% inclusive of an average indium content of the zone with the maximum indium content.
