Abstract
A method of fabricating nanowires or microwires employs a robust conductive surface whose edges define electrodes for promoting electrochemical deposition of nanowire material at those edges. Controlled deposition times and thin conductive layers allow extremely small diameter wires to be created and then removed without destruction of the pattern and the wires to be applied to a second substrate or used for composite materials.
Claims10
A method of constructing nanowires and microwires comprising the steps of:
- (a) applying a pattern of conductive diamond to a substrate, the pattern of conductive diamond providing edges of conductive diamond at desired locations of wires, the edges extending generally away from a surface of the substrate;
- (b) immersing the pattern in at least one solution containing an electrochemically depositable first material;
- and
- (c) controlling an application of an electrical potential between the conductive diamond and the solution to electrically deposit the first material along an edge to grow the wires.

A method of constructing nanowires and microwires comprising the steps of:
- (a) applying diamond conductor to a substrate, the diamond conductor providing edges at desired locations of wires;
- (b) immersing the pattern in a solution containing an electrochemically depositable material;
- and
- (c) controlling an application of an electrical potential between the edges and the solution to electrically deposit the material along at least a portion of the edges to grow the wire.
- (d) applying a cohesive material to the wires on the substrate;
- (e) removing the cohesive from the substrate material to pull the wires from the substrate;
- (f) repeating steps (d) and (e) for a given pattern and different second substrates.
