Nanostructures including controllably positioned and aligned synthetic nanotubes, and related methods

摘要

An integrated nanostructure comprises a microelectronic substrate having a surface; a catalyst disposed upon the surface of the microelectronic substrate and positioned thereupon within a first predetermined set of X and Y coordinates, wherein the catalyst is activated within a second predetermined set of X and Y coordinates defined within the surface of the microelectronic substrate; and a nanotube selectively disposed upon the activated second predetermined set of X and Y coordinates defined within the surface of the microelectronic substrate, such that the nanotube is controllably grown at a predetermined position upon the surface of the microelectronic substrate; wherein at least one selected from the group consisting of: (1) the disposition according to the first predetermined set of X and Y coordinates and (2) the activation of the catalyst according to the second predetermined set of X and Y coordinates is scaled with atomic precision.
