Gate controlled valley polarizer in bilayer graphene

Here, the authors present a gate-controlled valley-polarizer based on bilayer graphene, and through optimized device geometry and stacking method they obtain two orders of magnitude difference in conductance between the valley-polarized state and gapped states without the application of external mag...
