Abstract

The origin of strong valley polarization of electron wave transmitted through boundary between mono- and bi-layer graphenes can be ascribed to an evanescent wave in the bilayer graphene. The valley polarization is further enhanced across a ribbon-like region formed by partially overlapping of two monolayer graphenes.
