    • Given that the diffusion length is at least an order of magnitude larger than the observed dimension of the area of reduced WL thickness around the domes (Refs.), the length scale of the WL thickness variation is not set by diffusion. Thus, we attribute this observed length of the area of reduced WL thickness to the decay length of the strain fields surrounding the domes (Ref.)

    • Note that in contrast to the methods described in Refs., with this method the highly complex Ge composition profiles within the SiGe island cannot be resolved. However, no (extensive) post-measurement simulation is needed to extract the results
