Individually Addressable Conducting Polymer Nanowires Array

A facile technique for fabrication of individually addressable, conducting polymer nanowire arrays of controlled dimension, high aspect ratio, and site-specific positioning using electrodeposition between electrodes in channels created on semiconducting and insulating surfaces that can be easily scaled up is reported. In addition, the ability to create “arrays” of conducting polymer nanowires of same or different materials on the same chip has been demonstrated. The fidelity, quality, and electrical properties of single polypyrrole and polyaniline nanowires have been examined by SEM and I−V characteristics. Dendrite-free conducting polymer nanowires completely confined within the channels with full dimension control were observed. I−V characteristic of such nanowires show the ohmic nature of the contact with Au electrode.
