NANOSCALE WIRE METHODS AND DEVICES

摘要

The present invention generally relates to nanoscale wire methods and devices, including systems and methods for positioning nanoscale wires on a surface, and articles made therefrom. One aspect of the invention is generally directed to aligned nanoscale wires on a surface of a substrate, and systems and methods of positioning such nanoscale wires on the surface. In one set of embodiments, a first substrate is provided having a plurality of nanoscale wires, and at least some of the nanoscale wires are transferred to a second substrate by contacting at least some of the nanoscale wires with the second substrate, e.g., by moving or "sliding" the substrates relative to each other, in some cases causing alignment of the nanoscale wires on the second substrate. Another aspect of the invention is generally directed to electrical devices comprising a number of planes defined by nanoscale wires, e.g., in a "stacked" configuration. Yet other aspects of the invention are directed to nanoscale wires that can be used as sensors, e.g., in such devices. Still other aspects of the invention are directed to systems and methods for making and using such devices, kits involving the same, and the like.
