Claim:
1. An electronic device, comprising: a dielectric layer; a graphene layer including a first surface located upon the dielectric layer; and a first electrode, a second electrode, and a third electrode each separated from the graphene layer by the dielectric layer; wherein the first and second electrodes are spaced apart along the dielectric layer to define a first gap between the first and second electrodes; wherein the second and third electrodes are spaced apart along the dielectric layer to define a second gap between the second and third electrodes; wherein the sidewalls of the first and second electrodes defining the first gap are perpendicular with respect to a longitudinal axis of the electronic device and the sidewalls of the second and third electrodes defining the second gap are angled with respect to the longitudinal axis of the electronic device; wherein the graphene layer includes a second surface opposite the first surface; and wherein the electronic device includes:
