Abstract:
1. An electronic device comprising: a dielectric material; two electrode terminals, wherein a first of the two electrode terminals comprises a source and a second of the two electrode terminals comprises a drain; at least two independent carbon sheets forming a discontinuous carbon layer disposed between the two electrode terminals, wherein the discontinuous carbon layer is deposited on the dielectric material, said at least two independent carbon sheets are selected from a group consisting of graphene, graphite, and combinations thereof, and the electronic device exhibits a nonlinear current-versus-voltage response when operated over a voltage sweep range; and a channel length between the two electrode terminals, wherein the channel length is less than 1 μm, and the nonlinear current-versus-voltage response comprises at least about a 10-fold change in current over a voltage sweep range of about 0.5 V.
