Electronic properties of graphene hybrid materials from first-principles calculations

Graphene has been keeping a premier position not only in the field of the low-dimensional sciences but also in the semiconductor device due to its unique structural and electronic properties. However, graphene is a metal so that graphene is not utilized in logical electronic devices. Therefore, for realistic applications it is important to tune the electronic structure and to get a semiconducting graphene. In this presentation, I will theoretically demonstrate the possibility to tune the electronic structure of graphene by foreign materials, such as SiO2 substrate, ionic molecules, diamond that allow us to design the novel functional devices.
