Fabrication of Nanowires from Gold Nanoparticles by AC Dielectrophoresis and Ink-Jet Delivery
A process for nanowire fabrication from gold nanoparticles is described. In this process, we have combined the ink-jet delivery of a nanoparticle colloid with the dielectrophoresis technique. Ink-jet printing is used for the accurate delivery of gold nanoparticle colloid in an exact position and quantity. The nanoparticles dropped to a two electrode gap are ordered into nanowires by the dielectrophoresis force which is induced by the applied AC voltage. The nanowire structures are characterized by microscopy techniques and I-V measurements.
