Abstract

High-quality, single-crystalline silicon-germanium (Si(1-x)Gex) having a high germanium content is provided. Layers of the high-quality, single-crystalline silicon-germanium can be grown to high sub-critical thicknesses and then released from their growth substrates to provide Si(1-x)Gex films without lattice mismatch-induced misfit dislocations or a mosaic distribution of crystallographic orientations.
