Precise Manipulation and Alignment of Single Nanowire

Nanowires and nanotubes are being intensively investigated for nanoelectronic transport applications. The integration of such nanostructures into circuitry requires a simple, high-efficiency and low-cost strategy. Here we develop a single nanowire manipulating system to precisely manipulate and align the nanowire individually. We show that a single nanowire can be picked up through electromechanical force, transferred over different substrates and placed onto a pre-defined location. In addition, we have developed compatible fabrication processes to pattern all the aligned nanowires using one-level optical mask alignment. Representative test structures and a simple silicon nanowire transistor have been fabricated and demonstrated based on this approach.
