An Overview of the Electronic Structure of Monolayer Graphene

Monolayer graphene is a nanostructured material that consists of layers of graphene, each layer of single-layer graphene consists of a layer of carbon atoms that are interconnected in a hexagonal lattice. The crystal structure of monolayer graphene is two dimensional and carbon atoms are inserted in a hexagonal lattice. The band structure of monolayer graphene includes two main bands that located at points K and K’ considered as quantum bands of electrons and holes. The electronic properties of monolayer graphene include the movement of electrons at very high speed and maintaining their spin. Also, monolayer graphene has unique optical properties and can be used as an optical switcher in electronic devices. Which from the basis of the contemporary technology of graphene and is progressing, therefor, research in this field is important and this research was carried out in a library method and its purpose is to investigate the electronic structure of single – layer graphene.
