Claim Text:
1. An electronic device comprising: an insulator; a local first gate embedded in the insulator with a top surface of the first gate being substantially coplanar with a surface of the insulator; a first dielectric layer formed over the first gate and insulator; a channel comprising a bilayer graphene layer formed on the first dielectric layer, wherein the first dielectric layer provides a substantially flat surface on which the channel is formed; a second dielectric layer formed over the bilayer graphene layer, wherein the bilayer graphene layer provides a substantially flat surface on which the second dielectric layer is formed; and a local second gate formed over the second dielectric layer, each of the local first and second gates configured to be capacitively coupled to the channel of the bilayer graphene layer; wherein the local first and second gates form a first pair of gates to locally control a first portion of the bilayer graphene layer; and wherein the local first gate is controllable independent of the local second gate.
