Patent ID: 7829352

Claim:
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.
