High Rate Electric Field Driven Nanoelement Assembly on an Insulated Surface

摘要

A method for high rate assembly of nanoelements into two-dimensional void patterns on a non-conductive substrate surface utilizes an applied electric field to stabilize against forces resulting from pulling the substrate through the surface of a nanoelement suspension. The electric field contours emanating from a conductive layer in the substrate, covered by an insulating layer, are modified by a patterned photoresist layer, resulting in an increased driving force for nanoelements to migrate from a liquid suspension to voids on a patterned substrate having a non-conductive surface. The method can be used for the production of microscale and nanoscale circuits, sensors, and other electronic devices.

1. A device for assembling nanoelements, the device comprising a container for a suspension of nanoelements, a counter electrode disposed within the container, and a movable platform adapted for mounting a patterned substrate, the movable platform attached to a drive capable of pulling the platform through a surface of the suspension at a speed adjustable from about 0.5 to about 10 mm/min.
