Perfect valley filter in strained graphene with single barrier region
We present a single barrier system to generate pure valley-polarized current in monolayer graphene. A uniaxial strain is applied within the barrier region, which is delineated by localized magnetic field created by ferromagnetic stripes at the region’s boundaries. We show that under the condition of...
