  • Nanoscale wires and related devices
    Publication number: 20070281156
    Abstract: The present invention relates generally to sub-microelectronic circuitry, and more particularly to nanometer-scale articles, including nanoscale wires which can be selectively doped at various locations and at various levels. In some cases, the articles may be single crystals. The nanoscale wires can be doped, for example, differentially along their length, or radially, and either in terms of identity of dopant, concentration of dopant, or both. This may be used to provide both n-type and p-type conductivity in a single item, or in different items in close proximity to each other, such as in a crossbar array. The fabrication and growth of such articles is described, and the arrangement of such articles to fabricate electronic, optoelectronic, or spintronic devices and components.

  • Array-based architecture for molecular electronics
    Publication number: 20030200521
    Abstract: An architecture for nanoscale electronics is disclosed. The architecture comprises arrays of crossed nanoscale wires having selectively programmable crosspoints. Nanoscale wires of one array are shared by other arrays, thus providing signal propagation between the arrays. Nanoscale signal restoration elements are also provided, allowing an output of a first array to be used as an input to a second array. Signal restoration occurs without routing of the signal to non-nanoscale wires.
