Abstract:
1. A method of directing the growth of one or more nanostructures on a substrate, comprising the steps of: directing a charged particle beam-activated gas toward the surface of said substrate, said gas suitable for depositing onto the surface, by way of a reaction induced by a charged particle beam, a desired catalyst material capable of catalyzing the growth of a nanostructure; directing a charged particle beam at the substrate surface by scanning the beam over one or more desired locations on the surface and depositing the catalyst material only at said desired locations; and growing only a single nanostructure on the catalyst material at each desired location in a process catalyzed by the catalyst material, such that the location, shape, and size of the one or more nanostructures grown are controlled by the location, shape, and size of catalyst material deposited onto the surface at each desired location.
