Abstract

A method for forming an array of elongated nanostructures, includes in one embodiment, providing a substrate, providing a template having a plurality of pores on the substrate, and removing portions of the substrate under the plurality of pores of the template to form a plurality of cavities. A catalyst is provided in the plurality of cavities in the substrate, and the pores of the template are widened to expose the substrate around the catalyst so that the catalyst is spaced from the sides of the plurality of pores of the template. A plurality of elongated nanostructures is grown from the catalyst spaced from the sides of the pores of the template.
