    摘要: An optoelectronic semiconductor chip includes a semiconductor layer sequence having an active layer provided for generating radiation. The semiconductor chip can be operated in a first operating mode and in a second operating mode. The semiconductor layer sequence emits radiation in the first operating mode, while the semiconductor layer sequence emits no radiation in the second operating mode. The semiconductor layer sequence is operated in the forward direction in the first operating mode and in the reverse direction in the second operating mode. A display including a number of semiconductor chips of this type and a use as a motor vehicle headlight are furthermore specified.

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