Abstract
Because the charge transport property of graphene is superior to that of silicon, graphene is expected to be a good material of the next generation for electronic devices, and attracts much attention of researchers. Single-layered graphene is a zero band gap semiconductor. Accordingly, techniques of adjusting its band gap are necessary to its application. One of such techniques will be the use of bilayer graphene. In this article, the stable structure of bilayer graphene is obtained by means of molecular dynamics. And the band structures of the local parts of the stable structure are calculated by means of first-principles calculation. It turns out that the magnitude of the band gap is changed by shifting the relative configuration of the two layers of bilayer graphene.
