Abstract
The present disclosure generally describes methods for forming nanowires on a substrate, where carbon nanotubes may be placed in a pattern on a surface of a substrate. The surface of the substrate may be exposed to conditions such that carbothermal reduction occurs between the carbon nanotubes and the substrate to form nanotrenches in the pattern, and a conductive material may be deposited into the nanotrenches for forming nanowires.

A method for forming nanowires on a substrate, the method comprising:
- placing carbon nanotubes in a pattern on at least a portion of a surface of a substrate;
- applying a temperature and a pressure at least to the portion of the surface of the substrate over a period of time sufficient to cause formation of nanotrenches according to the pattern;
- and
- depositing a conductive material into the nanotrenches for forming at least one or more nanowires having the pattern on the substrate, wherein the conductive material is at least partially electrically conductive.
A method for forming nanowires on a substrate, comprising:
- placing carbon nanotubes in a pattern on at least a portion of a surface of a substrate, wherein at least a portion of the carbon nanotubes on the surface of the substrate are substantially aligned with respect to each other;
- applying a temperature and a pressure at least to the portion of the surface of the substrate over a period of time sufficient to etch nanotrenches in the pattern;
- depositing a metal on the substrate such that the nanotrenches are filled with the deposited metal and such that a layer of the deposited metal is formed about the surface of the substrate;
- and
- etching at least a portion of the layer of the metal from the surface of the substrate so that metal remains in the nanotrenches of the substrate to form nanowires, wherein at least a portion of the nanowires are substantially aligned according to a pattern of the nanotrenches of the substrate.
An electrically conducting structure, comprising:
- a substrate defining a pattern of nanotrenches having a depth in a range of approximately 1 nm to approximately 10 nm from a surface of the substrate;
- and
- a conductive material disposed inside the nanotrenches, wherein the conductive material is electrically conductive.
A computer-readable medium comprising computer readable instructions which are provided for forming nanowires on a substrate wherein, when a processing arrangement executes the instructions, the processing arrangement is configured for:
- placing carbon nanotubes in a pattern on at least a portion of a surface of a substrate;
- applying a temperature and a pressure at least to the portion of the surface of the substrate over a period of time sufficient to cause formation of nanotrenches according to the pattern;
- and
- depositing a conductive material into the nanotrenches for forming at least one or more nanowires having the pattern on the substrate, wherein the conductive material is at least partially electrically conductive.
