| 摘要 |
The present invention relates to a compliant substrate having a top surface for receiving a heteroepitaxial structure or heteroepitaxial layer. This substrate comprises a carrier substrate, a top single-crystalline layer, a buried layer located between the carrier substrate and the top layer, and a weakened region located in the top layer or between the top layer and the buried layer such that the compliant substrate facilitates relaxed growth of a heteroepitaxial layer or structure upon the top surface. The invention also relates to the combination of the compliant substrate and a heteroepitaxial layer provided thereon, as well as to a method of making the compliant substrate and combination.
