Abstract
The self-assembly of nanoscale components into 2D arrays is of interest for the development of nanoelectronic and nanophotonic circuitry. We have constructed 2D arrays of alternating rows of different-sized Au nanoparticles by sequence-encoded self-assembly to DNA scaffolding, thereby demonstrating the potential of this approach for assembling complex arrays of components. We have exploited this technique further to demonstrate templated growth of metallic nanowires by the catalytic conversion of DNA-assembled Au nanoparticles into parallel wires. Here, we report the electrical characteristics of such nanowires contacted by narrow, e-beam patterned electrodes. The nanowire devices exhibit linear current-voltage characteristics and single-electron tunneling features at room temperature. These results demonstrate that this approach, in addition to offering a means for precise, programmable component layout, can provide the passive, low-leakage electrical environment needed for nanoelectronic circuitry.
