International Classification:

B82Y 99/00

US Classification:

257746, 204451, 977773, 977742, 977762, 977842, 977840, 257E23017

Abstract:

The invention provides a fast, scalable, room temperature process for fabricating metallic nanorods from nanoparticles or fabricating metallic or semiconducting nanorods from carbon nanotubes suspended in an aqueous solution. The assembled nanorods are suitable for use as nanoscale interconnects in CMOS-based devices and sensors. Metallic nanoparticles or carbon nanotubes are assembled into lithographically patterned vias by applying an external electric field. Since the dimensions of nanorods are controlled by the dimensions of vias, the nanorod dimensions can be scaled down to the low nanometer range. The aqueous assembly process is environmentally friendly and can be used to make nanorods using different types of metallic particles as well as semiconducting and metallic nanaotubes.

US Classification:

174257, 204485, 204622, 174258

Abstract:

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 micro scale and nanoscale circuits, sensors, and other electronic devices.

International Classification:

C25D 13/18

Abstract:

A variety of homogeneous or layered hybrid nanostructures are fabricated by electric field-directed assembly of nanoelements. The nanoelements and the fabricated nanostructures can be conducting, semi-conducting, or insulating, or any combination thereof. Factors for enhancing the assembly process are identified, including optimization of the electric field and combined dielectrophoretic and electrophoretic forces to drive assembly. The fabrication methods are rapid and scalable. The resulting nanostructures have electrical and optical properties that render them highly useful in nanoscale electronics, optics, and biosensors.
