Abstract:
A semiconductor structure can include a substrate and a substrate layer. The substrate can be formed of silicon and the substrate layer can be formed of silicon germanium. Above the substrate and under the substrate layer there can be provided a multilayer substructure. The multilayer substructure can include a first layer and a second layer. The first layer can be formed of a first material and the second layer can be formed of second material. A method can include forming a multilayer substructure on a substrate, annealing the multilayer substructure, and forming a substrate layer on the multilayer substructure.
