Contrary to other sp2 systems, such as fullerenes or nanotubes, where defect and/or edge effects are often negligible, electronic and transport properties of graphene nanostructures result to be highly sensitive to the edge morphology and termination. New intrinsic features related to the presence of specific edge configurations have been studied in depth in the last few years, above all from a theoretical point of view.
Here, we concentrate on the role played by the presence of a magnetic substrate or by edge functionalization and morphology in determining structural stability, electronic and optical properties of prototypical graphene nanostructures. Depending on the specific system and physical issue, we have made use of different theoretical methods, ranging from Hartree-Fock based semiempirical approches to ab initio density-functional theory and many-body techniques.
