A technique is provided for performing sequencing with a nanodevice. Alternating graphene layers and dielectric layers are provided one on top of another to form a multilayer stack of heterojunctions. The dielectric layers include boron nitride, molybdenum disulfide, and/or hafnium disulfide layers. A nanopore is formed through the graphene layers and the dielectric layers. The graphene layers are individually addressed by applying individual voltages to each of the graphene layers on a one to one basis when a particular base of a molecule is in the nanopore. Each of the graphene layers is an electrode. Individual electrical currents are measured for each of the graphene layers as the particular base moves from a first graphene layer through a last graphene layer in the nanopore. The base is identified according to the individual electrical currents repeatedly measured for the base moving from the first through last graphene layer in the nanopore. |
