Abstract
Nanopores for single-electron devices may be used as templates for placing of a desired number of nanoparticles at a desired location in the devices. Nanopores may be fabricated by providing on a substrate spaced apart electrode regions, a spacer region therebetween, and a cover layer on the spaced apart electrode regions and on the spacer region. A wet etching solution is contacted to the cover-layer. At least one of the spaced apart electrode regions is energized, to selectively wet etch the cover layer adjacent the spacer region and define a nanopore in the cover layer adjacent the spacer region. At least one nanoparticle is placed in the nanopore. Accordingly, nanopores can be aligned to a buried spacer region.
