摘要： A method for is disclosed for fabricating diluted magnetic semiconductor (DMS) nanowires by providing a catalyst-coated substrate and subjecting at least a portion of the substrate to a semiconductor, and dopant via chloride-based vapor transport to synthesize the nanowires. Using this novel chloride-based chemical vapor transport process, single crystalline diluted magnetic semiconductor nanowires Ga1-xMnxN (x=0.07) were synthesized.

摘要： Fluidic nanotube devices are described in which a hydrophilic, non-carbon nanotube, has its ends fluidly coupled to reservoirs. Source and drain contacts are connected to opposing ends of the nanotube, or within each reservoir near the opening of the nanotube. The passage of molecular species can be sensed by measuring current flow (source-drain, ionic, or combination). The tube interior can be functionalized by joining binding molecules so that different molecular species can be sensed by detecting current changes. The nanotube may be a semiconductor, wherein a tubular transistor is formed. A gate electrode can be attached between source and drain to control current flow and ionic flow. By way of example an electrophoretic array embodiment is described, integrating MEMs switches. A variety of applications are described, such as: nanopores, nanocapillary devices, nanoelectrophoretic, DNA sequence detectors, immunosensors, thermoelectric devices, photonic devices, nanoscale fluidic bioseparators, imaging devices, and so forth.

摘要： Vertical integrated field effect transistor circuits and methods are described which are fabricated from Silicon, Germanium, or a combination Silicon and Germanium based on nanowires grown in place on the substrate. By way of example, vertical integrated transistors are formed from one or more nanowires which have been insulated, had a gate deposited thereon, and to which a drain is coupled to the exposed tips of one or more of the nanowires. The nanowires are preferably grown over a surface or according to a desired pattern in response to dispersing metal nanoclusters over the desired portions of the substrate. In one preferred implementation, SiCl4 is utilized as a gas phase precursor during the nanowire growth process. In place nanowire growth is also taught in conjunction with structures, such as trenches, while bridging forms of nanowires are also described.

摘要： A two-layer nanotape that includes a nanoribbon substrate and an oxide that is epitaxially deposited on a flat surface of the nanoribbon substrate is described. The oxide is deposited on the substrate using a pulsed laser ablation deposition process. The nanoribbons can be made from materials such as SnO2, ZnO, MgO, Al2O3, Si, GaN, or CdS. Also, the sintered oxide target can be made from materials such as TiO2, transition metal doped TiO2 (e.g., CO0.05Ti0.95O2), BaTiO3, ZnO, transition metal doped ZnO (e.g., Mn0.1Zn0.9O and Ni0.1Zn0.9O), LaMnO3, BaTiO3, PbTiO3, YBa2Cu3Oz, or SrCu2O2 and other p-type oxides. Additionally, temperature sensitive nanoribbon/metal bilayers and their method of fabrication by thermal evaporation are described. Metals such as Cu, Au, Ti, Al, Pt, Ni and others can be deposited on top of the nanoribbon surface. Such devices bend significantly as a function of temperature and are suitable as, for example, thermally activated nanoscale actuators.

摘要： Methods of fabricating uniform nanotubes are described in which nanotubes were synthesized as sheaths over nanowire templates, such as using a chemical vapor deposition process. For example, single-crystalline zinc oxide (ZnO) nanowires are utilized as templates over which gallium nitride (GaN) is epitaxially grown. The ZnO templates are then removed, such as by thermal reduction and evaporation. The completed single-crystalline GaN nanotubes preferably have inner diameters ranging from 30 nm to 200 nm, and wall thicknesses between 5 and 50 nm. Transmission electron microscopy studies show that the resultant nanotubes are single-crystalline with a wurtzite structure, and are oriented along the direction. The present invention exemplifies single-crystalline nanotubes of materials with a non-layered crystal structure. Similar “epitaxial-casting” approaches could be used to produce arrays and single-crystalline nanotubes of other solid materials and semiconductors. Furthermore, the fabrication of multi-sheath nanotubes are described as well as nanotubes having multiple longitudinal segments.
