    摘要: The semiconductor layer structure includes an active layer (6) and a superlattice (9) composed of stacked layers (9a, 9b) of III-V compound semiconductors of a first (a) and at least one second type (b). Adjacent layers of different types in the superlattice (9) differ in composition with respect to at least one element. The layers (9a, 9b) have predefined layer thicknesses, such that the layer thicknesses of layers (9a) of the first type (a) and of the layers (9b) of the second type (b) increase from layer to layer with increasing distance from an active layer (6). An increasing layer thickness within the layers of the first and the second type (a, b) is suitable for adapting the electrical, optical and epitaxial properties of the superlattice (9) to given requirements in the best possible manner.
