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
Claims21
A template for growing nanowires or microwires comprising:
- an insulating layer providing a substrate;
- a pattern of conductor positioned over the insulating layer providing edges at desired locations of wires;
- and
- a second insulating layer covering the pattern of conductor except at the edges and without overhang of the edges of the conductor by the insulating layer along a direction normal to a surface of the substrate at the edges;
- and
- wherein the insulating layers and conductor are selected to permit physical detachment of wires grown thereon by cohesive forces without substantial damage to the insulating layers and conductor.
