    摘要: A locally gated graphene nanostructure is described, along with methods of making and using the same. A graphene layer can include first and second terminal regions separated by a substantially single layer gated graphene nanoconstriction. A local first gate region can be separated from the graphene nanoconstriction by a first gate dielectric. The local first gate region can be capacitively coupled to gate electrical conduction in the graphene nanoconstriction. A second gate region can be separated from the graphene nanoconstriction by a second gate dielectric. The second gate region can be capacitively coupled to provide a bias to a first location in the graphene nanoconstriction and to a second location outside of the graphene nanoconstriction. Methods of making and using locally gated graphene nanostructures are also described.
