Abstract:
1. A method for forming molecular electronic devices, comprising: (a) providing an electrically conducting substrate having a first major surface and a second major surface, substantially parallel to said first major surface; (b) forming an etch mask on said first major surface, said etch mask comprising at least one nanoparticle; (c) directionally etching said electrically conducting substrate from said first major surface toward said second major surface, using said etch mask to protect underlying portions of said electrically conducting substrate against said etching, thereby forming at least one pillar underneath said etch mask and forming a new surface of the electrically conducting substrate upon which the at least one pillar is formed; (d) forming a layer of insulating material on said etched electrically conducting substrate, including around said at least one pillar and at least partially covering said at least one pillar; (e) removing said at least one pillar to leave at least one nanopore in said insulating layer and to expose portions of the new surface of the electrically conducting substrate; and (f) dispersing electrically switchable molecules in said at least one nanopore.
