Abstract

We recently proposed an ultrafast DNA sequencing method that electrically distinguishes different nucleobases on a graphene nanoribbon (GNR), utilizing π–π interaction. Analyzing the molecular orbitals (MOs) and the features of dips in conductance for our GNR-based sequencing device, we prove that the Fano resonance is responsible for the characteristic dips of each nucleobase.
