Abstract
This disclosure relates to a system and method for creating nano-object arrays. A nano-object array can be created by exposing troughs in a corrugated surface to nano-objects and depositing the nano-objects within or orienting the nano-objects with the troughs.
Claims34
A method for fabricating an array of nano-objects comprising:
- providing a superlattice having a working surface and alternating layers of a conductive material and one or more other materials, the working surface comprising exposed edges of the alternating layers, the exposed edges of the conductive material layers being offset to form troughs relative to the exposed edges of one or more of the one or more other material layers and having a length and a thickness, the length being significantly larger than the thickness and the thickness being between 0.7 and one hundred nanometers;
- charging nano-objects in a liquid bath, the charged nano-objects having a length and a thickness, the length being significantly larger than the thickness, the thickness of the charged nano-objects being less than the thickness of the exposed edges of the conductive material layers;
- placing the working surface in the bath;
- charging the offset, exposed edges of the conductive material layers to create a voltage difference between the offset, exposed edges of the conductive material layers and the charged nano-objects;
- and
- collecting the charged nano-objects in the troughs to create an array of the nano-objects.

A method for fabricating an array of nano-objects comprising:
- charging nano-objects;
- charging, relative to the charged nano-objects, troughs of a corrugated surface of a superlattice, the corrugated surface having ridges being substantially uncharged relative to the nano-objects;
- exposing the surface to the charged nano-objects to create, within the troughs, an array of the charged nano-objects, wherein the charged nano-objects are ions within a bath and the exposing includes placing the surface within the bath.
An apparatus comprising:
- means for charging nano-objects;
- means for charging, relative to the charged nano-objects, troughs of a corrugated surface, the corrugated surface having ridges being substantially uncharged relative to the nano-objects;
- means for exposing the surface to the charged nano-objects to collect, within the troughs, a first array of the charged nano-objects, wherein the means for exposing is a flow of the charged nano-objects along the troughs.
