| 1. A method for fabricating a patterned array of metallic nanostructures, comprising:
catalytically growing a plurality of nanowires on a surface of a substrate, the surface of the substrate comprising a crystalline
material, said plurality of nanowires being laterally arranged on said substrate in a predetermined, periodic, two-dimensional-array
pattern;
coating said plurality of nanowires with a metal to generate a plurality of metal-coated nanowires having vacancies therebetween;
stabilizing said metal-coated nanowires by filling in said vacancies with a sacrificial material;
planarizing said stabilized metal-coated nanowires; and
removing said sacrificial material, said patterned array of metallic nanostructures being formed by said plurality of planarized
metal-coated nanowires.
