A method of forming a graphene device includes: providing a glass substrate with a blocking layer disposed thereon to form a stack; providing a first electrode and a second electrode; increasing the temperature of the stack to at least 100° C.; applying an external electric field (V) to the first electrode such that at least one metal ion of the glass substrate migrates toward the first electrode to create a depletion region in the glass substrate adjacent the second electrode; decreasing the temperature of the stack to room temperature while applying the external electric field to the first electrode; and after reaching room temperature, setting the external electric field to zero to create a frozen voltage region adjacent the second electrode.
