摘要: We report the first experimental study of continuous sheets graphene possessing both one-layer and two-layer portions. In a bulk hybrid structure featuring two large-area areas, our measurements in magnetic field revealed formation independent sets Landau levels with drastically different energy scales level spacings as expected well new features quantum oscillation originating from interface device configuration. edge hybrids large narrow edges, we observed an anomalous suppression amplitude graphene. The is interpreted consequence locking Fermi energies, associated charge imbalance, emergence chiral states, whose physical consequences are yet to be fully understood.
