We report a novel design of graphene as electrical sensor for single-molecule detection, by employing natural self-assembly properties of graphene/multilayered h-BN/graphene for single-molecule detection. The novelty of our design is that we use the top and bottom graphene layers as two separate electrodes while the sandwiched h-BN layers as the insulating dielectric. Our theoretical study indicates that the ordered stacking of h-BN dielectric in the nanopore will result in intriguing quantum interference effects, which can be utilized for enhancing the sensitivity of the proposed device.
