▎ 摘  要

We investigate the quantum transport through zigzag graphene nanoribbons with embedded "5-7-5"-edge line defects, by means of the non-equilibrium Green's function technique. It is found that when two semi-infinite line defects exist in the nanoribbon, notable Fano antiresonance takes place in the quantum transport process, which enables to drive the apparent thermoelectric effect. We propose this structure to be a promising candidate for improving the thermoelectric efficiency based on graphene nanoribbons. (C) 2018 Elsevier B.V. All rights reserved.
