| Abstract: | We investigate the electronic properties of Graphene Nanoribbon under a tight - binding frame, and further we get the edge state of the Zigzag Ribbon and the band gap of the Archair ribbon. Then, we calculate the transport properties of some devices based on the grapheme nanoribbon combining a Green＇ s function formulism, and we get a rectification in the doped nanoribon. |
