  • Patent number: 8471240
    Abstract: An optoelectronic component including a semiconductor layer structure, the semiconductor layer structure including a superlattice composed of stacked layers of III-V compound semiconductors of a first and at least one second type. Adjacent layers of different types in the superlattice differ in composition with respect to at least one element, at least two layers of the same type having a different content of the at least one element, the content of the at least one element is graded within a layer of the superlattice, and the layers of the superlattice contain dopants in predefined concentrations, with the superlattice comprising layers that are doped with different dopants. In this way, the electrical, optical and epitaxial properties of the superlattice can be adapted in the best possible manner to given requirements, particularly epitaxial constraints.

  • Patent number: 8022392
    Abstract: The semiconductor layer structure includes an active layer and a superlattice composed of stacked layers of III-V compound semiconductors of a first and at least one second type. Adjacent layers of different types in the superlattice differ in composition with respect to at least one element. The layers have predefined layer thicknesses, such that the layer thicknesses of layers of the first type and of the layers of the second type increase from layer to layer with increasing distance from an active layer. An increasing layer thickness within the layers of the first and the second type is suitable for adapting the electrical, optical and epitaxial properties of the superlattice to given requirements in the best possible manner.

  • Publication number: 20080054252
    Abstract: 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.
