This booklet displays the present prestige of theoretical and experimental examine of graphene established nanostructures, particularly quantum dots, at a degree obtainable to younger researchers, graduate scholars, experimentalists and theorists. It offers the present country of analysis of graphene quantum dots, a unmarried or few monolayer thick islands of graphene. It introduces the reader to the digital and optical homes of graphite, intercalated graphite and graphene, together with Dirac fermions, Berry's part linked to sublattices and valley degeneracy, covers unmarried particle homes of graphene quantum dots, electron-electron interplay, magnetic homes and optical homes of gated graphene nanostructures. The digital, optical and magnetic houses of the graphene quantum dots as a functionality of dimension, form, kind of part and provider density are thought of. specified cognizance is paid to the knowledge of edges and the emergence of aspect states for zigzag edges. Atomistic tight binding and powerful mass methods to unmarried particle calculations are played. in addition, the theoretical and numerical therapy of electron-electron interactions on the mean-field, HF, DFT and configuration-interaction point is defined intimately.
