    摘要: The present invention is directed to systems and methods for nanowire growth. In an embodiment, methods for nanowire growth and doping are provided, including methods for epitaxial vertically oriented nanowire growth including providing a substrate material having one or more nucleating particles deposited thereon in a reaction chamber, introducing an etchant gas into the reaction chamber at a first temperature which gas aids in cleaning the surface of the substrate material, contacting the nucleating particles with at least a first precursor gas to initiate nanowire growth, and heating the alloy droplet to a second temperature, whereby nanowires are grown at the site of the nucleating particles. The etchant gas may also be introduced into the reaction chamber during growth of the wires to provide nanowires with low taper.

    摘要: The present invention is directed to nanowire structures and interconnected nanowire networks comprising such structures, as well as methods for their production. The nanowire structures comprise a nanowire core, a carbon-based layer, and in additional embodiments, carbon-based structures such as nanographitic plates consisting of graphenes formed on the nanowire cores, interconnecting the nanowire structures in the networks. The networks are porous structures that can be formed into membranes or particles. The nanowire structures and the networks formed using them are useful in catalyst and electrode applications, including fuel cells, as well as field emission devices, support substrates and chromatographic applications.

    摘要: The compositions, methods and systems of the invention provide nanocrystal taggants for unobtrusive monitoring of objects. Objects can be tagged with nanocrystal taggant compositions for detection of informative invisible emissions on illumination with appropriate excitation wavelengths. Authentication schemes are also provided that takes advantage of the unique emission and absorption characteristics of nanocrystals to create a unique spectral code that is far more difficult to decode and replicate than those previously employed.

At least a portion of the source contact and/or the drain contact overlaps with the gate contact along the nanowire the length. In another aspect, an electronic device includes a nanowire having a semiconductor core surrounded by an insulating shell layer. A ring shaped first gate region surrounds the nanowire along a portion of the length of the nanowire. A second gate region is positioned along the length of the nanowire between the nanowire and the substrate. A source contact and a drain contact are coupled to the semiconductor core of the nanowire at respective exposed portions of the semiconductor core.

    摘要: Methods and apparatuses for electronic devices such as non-volatile memory devices are described. The memory devices include a multi-layer control dielectric, such as a double or triple layer. The multi-layer control dielectric includes a combination of high-k dielectric materials such as aluminum oxide, hafnium oxide, and/or hybrid films of hafnium aluminum oxide.
