Patent ID: 8227179

Claim:
A method for manufacturing cross-structures of nanostructures comprising: providing a substrate; patterning a first mask layer on the substrate; adsorbing first nanostructures onto the substrate having the first mask layer, wherein the first nanostructure are adsorbed onto first exposed regions of the substrate unmasked by the first mask layer; removing the first mask layer from the substrate having the first nanostructures adsorbed onto the first exposed regions of the substrate unmasked by the first mask layer; patterning a second mask layer on the substrate after the removing of the first mask layer; and adsorbing second nanostructures onto the substrate having the second mask layer, wherein the second nanostructures are adsorbed onto second exposed regions of the substrate unmasked by the second mask layer, and wherein the second nanostructures are adsorbed under conditions effective to manufacture cross-structures of nanostructures.
