  • Publication number: 20050253137
    Abstract: The present invention relates generally to nanotechnology and sub-microelectronic circuitry, and more particularly to nanoelectronics. One aspect of the invention is directed to nanostructures on substrates. In some cases, the substrate may be or comprise glass and/or polymers, and in some cases, the substrate may be flexible and/or transparent. The present invention is also directed, according to another aspect, to techniques for fabricating nanostructures on substrates. For example, monolayers of nanoscale semiconductors may be etched, e.g. photolithographically, to yield discrete and/or predetermined arrays of nanoscale semiconductors and other articles on a substrate. In one embodiment, the array may include hundreds, thousands, or more of electronic components such as field-effect transistors. Such arrays may be connected to electrodes using photolithographic techniques, and in some cases, without the need for registering individual semiconductor-metal contacts.

  • Publication number: 20050164432
    Abstract: A bulk-doped semiconductor that is at least one of the following: a single crystal, an elongated and bulk-doped semiconductor that, at any point along its longitudinal axis, has a largest cross-sectional dimension less than 500 nanometers, and a free-standing and bulk-doped semiconductor with at least one portion having a smallest width of less than 500 nanometers. Such a semiconductor may comprise an interior core comprising a first semiconductor; and an exterior shell comprising a different material than the first semiconductor. Such a semiconductor may be elongated and my have, at any point along a longitudinal section of such a semiconductor, a ratio of the length of the section to a longest width is greater than 4:1, or greater than 10:1, or greater than 100:1, or even greater than 1000:1.

  • Publication number: 20050117441
    Abstract: Electrical devices comprised of nanoscopic wires are described, along with methods of their manufacture and use. The nanoscopic wires can be nanotubes, preferably single-walled carbon nanotubes. They can be arranged in crossbar arrays using chemically patterned surfaces for direction, via chemical vapor deposition. Chemical vapor deposition also can be used to form nanotubes in arrays in the presence of directing electric fields, optionally in combination with self-assembled monolayer patterns. Bistable devices are described.

  • Publication number: 20050064731
    Abstract: Nanowires are disclosed which comprise transition metal oxides. The transition metal oxides may include oxides of group II, group III, group IV and lanthanide metals. Also disclosed are methods for making nanowires which comprise injecting decomposition agents into a solution comprising solvents and metallic alkoxide or metallic salt precursors.
