Abstract:
1. A method of fabricating a nanoscale interconnect by electrical field directed assembly of nanoelements, the method comprising the steps of: (a) providing a nanosubstrate comprising a base layer, a conductive layer deposited onto the base layer, and an insulating layer deposited onto the conductive layer, the insulating layer comprising a via, the via forming a void in the insulating layer and defining a pathway through the insulating layer that exposes the conductive layer; (b) contacting the nanosubstrate with an aqueous suspension of nanoelements; and (c) applying an essentially uniform electrical field between the conducting layer and an electrode in the suspension, the electrical field consisting of the sum of a DC voltage and an AC voltage; wherein the nanosubstrate and the suspension electrode are substantially planar, and wherein the shape and size of the nanosubstrate and the suspension electrode are substantially the same, whereby nanoelements from the suspension migrate into the via to form a nanoscale interconnect having an electrical connection with the conductive layer.
