摘要：
Using nonequilibrium Green's functions in combination with density functional theory, we investigated the electronic transport behaviors of single layer zigzag graphene Nano-ribbon (ZGNR) with a Carbon vacancy in edge. The results show that electronic transport properties of the asymmetry ZGNR can be modulated by vacancy in edges, and prominent negative differential resistance (NDR) can be observed. These results may be useful for designing practical devices based on graphene Nano-ribbons.
