Abstract:
1. A method of forming a switch, comprising: forming a bottom electrode over a base; forming a first electrically conductive structure directly over the bottom electrode; forming dielectric material along a sidewall of the first electrically conductive structure, the first electrically conductive structure and the dielectric material together covering a first portion of the bottom electrode and leaving a second portion of the bottom electrode exposed; forming a graphene structure electrically coupled with the exposed portion of the bottom electrode, along the dielectric material and laterally spaced from the first electrically conductive structure by the dielectric material; forming a second electrically conductive structure on an opposing side of the graphene structure from the first electrically conductive structure, the second electrically conductive structure being directly over the bottom electrode; forming a top electrode over the graphene structure; the bottom electrode being electrically coupled with one of the first and second electrically conductive structures, the top electrode being electrically coupled with the other of the first and second electrically conductive structures; and wherein the first and second electrically conductive structures are configured to provide an electric field across the graphene structure.
