Abstract: Using first-principles electronic structure and transport calculations the electronic structure and transport properties of single layer armchair graphene nanoribbons with zigzag edges and the effect of edge-vacancy defects were investigated. It was shown that perfect armchair graphene nanoribbons were metallic ribbons. Though the electronic band structure may be affected by the edge-vacancy defects, they remain the metallic characteristic.

Key words: Graphene nanoribbons, Vacancy defects, Electronic structure, Transport property
