(Color online) Schematic illustration of the bilayer graphene device for the creation of a kink potential. Applied gated voltage to the upper and lower layers with opposite sign induce a spacial dependent electric field Ee. An external magnetic field , is applied perpendicular to the bilayer graphene sheets.
