  • Patent number: 9252214
    Abstract: Disclosed is a method to construct a device that includes a plurality of nanowires (NWs) each having a core and at least one shell. The method includes providing a plurality of radially encoded NWs where each shell contains one of a plurality of different shell materials; and differentiating individual ones of the NWs from one another by selectively removing or not removing shell material within areas to be electrically coupled to individual ones of a plurality of mesowires (MWs). Also disclosed is a nanowire array that contains radially encoded NWs, and a computer program product useful in forming a nanowire array.
    Type: Grant

  • Patent number: 6963077
    Abstract: A memory array comprising nanoscale wires is disclosed. The nanoscale wires are addressed by means of controllable regions axially and/or radially distributed along the nanoscale wires. In a one-dimensional embodiment, memory locations are defined by crossing points between nanoscale wires and microscale wires. In a two-dimensional embodiment, memory locations are defined by crossing points between perpendicular nanoscale wires. In a three-dimensional embodiment, memory locations are defined by crossing points between nanoscale wires located in different vertical layers.

  • Patent number: 6900479
    Abstract: A method for controlling electric conduction on nanoscale wires is disclosed. The nanoscale wires are provided with controllable regions axially and/or radially distributed. Controlling those regions by means of microscale wires or additional nanoscale wires allows or prevents electric conduction on the controlled nanoscale wires. The controllable regions are of two different types. For example, a first type of controllable region can exhibit a different doping from a second type of controllable region. The method allows one or more of a set of nanoscale wires, packed at sublithographic pitch, to be independently selected.
