Scientific paper

We study the states localized near an interface between conducting and insulating bilayer graphene (BLG) and show that they have highly unusual properties that have no analog in conventional systems. Moreover, the states belonging to the two independent valleys in the Brillouin zone of BLG show contrasting properties that allows a relatively easier experimental realization of various valley based functionalities desired in valleytronics without requiring any sophisticated techniques.
