Electronic properties of hybrid graphene/silicene nanocomposite

Abstract

Like graphene, silicene is a monolayer of silicon atoms in a hexagonal lattice, which has the same unique properties as graphene. However, the synthesis of silicene remains a problem because of the fairly rapid oxidation of silicene in air. Van der Waals structures obtained by superimposing layers of isolated two-dimensional atomic crystals such as graphene (G) and silicene (Si) provide the stability of silicene, which opens up opportunities for widespread use of silicene for the development of future multifunctional devices. In the present work, within the framework of the density functional theory, the electronic properties of the graphene-silicene (G/Si) hybrid nanocomposite are studied.
