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.

Abstract: Electronic devices for the generation of electromagnetic radiation are provided. Also provided are methods for using the devices to generate electromagnetic radiation. The radiation sources include an anisotropic electrically conducting thin film that is characterized by a periodically varying charge carrier mobility in the plane of the film. The periodic variation in carrier mobility gives rise to a spatially varying electric field, which produces electromagnetic radiation as charged particles pass through the film.

Abstract: Semiconductor trilayer structures that are doped and strained are provided. Also provided are mechanically flexible transistors, including radiofrequency transistors, incorporating the trilayer structures and methods for fabricating the trilayer structures and transistors. The trilayer structures comprise a first layer of single-crystalline semiconductor material, a second layer of single-crystalline semiconductor material and a third layer of single-crystalline semiconductor material. In the structures, the second layer is in contact with and sandwiched between the first and third layers and the first layer is selectively doped to provide one or more doped regions in the layer.
