In this work, we performed a theoretical investigation of a nanogap-based all electronic DNA sequencing device. To do so, we used a nitrogen-terminated nanogap on a graphene sheet with the environment fully taken into account. Our investigation is performed using a hybrid methodology combining quantum and classical mechanics coupled to non-equilibrium Green's functions for solving the electron transport across the device. The obtained results show that the DNA nucleotides can ","authors_text":"Alexandre Reily Rocha, Ernane de Freitas Martins, Gustavo Troiano Feliciano, Ralph Hendrik Scheicher, Rodrigo G.
