Effect of point defect in the electronic structure of single layer graphene on Cu substrate

Point defect in mono-layer graphene on Cu substrate shows significant change in electronic structure in comparison to without the presence of defect. Our attempt to observe the electronic structure of mono-layer graphene on Cu substrate shows the band-structure, binding energy and density of states. Well established density functional theory (DFT) calculation has been performed to study the stability and scalability and other physical properties of the structure. Study of vacancy in graphene on Cu substrate therefore can be a new platform for study of disordered graphene and such study could be a benchmark for the field of electronics.
