Abstract: PURPOSE: A method for manufacturing cross-structures of nanostructures is provided to prepare cross-structures such as nanotubes or nanowires. CONSTITUTION: A method for manufacturing cross-structures of nanostructures comprises the steps of: providing a substrate(110); patterning a first mask layer(120) on a substrate; adsorbing first nanostructures(130) on surface regions of a substrate in which a first mask layer does not exist; removing the substrate from the first mask layer; patterning a second mask layer(140) on the substrate in which first nanostructureses are assembled; and adsorbing second nanostructures(150) on the surface regions of the substrate in which the second mask layer does not exist.

Abstract: Techniques for manufacturing cross-structures of nanostructures, such as nanowires and carbon nanotubes are provided. In one embodiment, a method for manufacturing cross-structures of nanostructures include providing a substrate, patterning a first mask layer on the substrate, adsorbing first nanostructures onto surface regions of the substrate where the first mask layer does not exist, removing the first mask layer from the substrate, patterning a second mask layer on the substrate to which the first nanostructures are adsorbed, and adsorbing second nanostructures onto the surface regions of the substrate where the second mask layer does not exist, under conditions effective to manufacture cross-structures of nanostructures on the substrate.
