It relies on innovative real space computational methods of the time-dependent spreading of electronic wave packets. First a universal scaling law of the elastic mean free path versus the average grain size is predicted for polycrystalline morphologies, and charge mobilities of up to 300.000 cm2/V.s are determined for 1 micron grain size, while amorphous graphene membranes are shown to behave as Anderson insulators. An unprecedented spin relaxation mechanism, unique to graphene and driven by spin/pseudospin entanglement is then reported in the presence of weak spin-orbit interaction (gold ad-atom impurities) together with the prediction of a crossover from a quantum spin Hall Effect to spin Hall effect (for thallium ad-atoms), depending on the degree of surface ad-atom segregation and the resulting island diameter.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053NanoscienceNanoscienceNanostructuresOptical materialsElectronicsMaterialsMaterials—SurfacesThin filmsNanoscale Science and Technologyhttps://scigraph.springernature.com/ontologies/product-market-codes/P25140Optical and Electronic Materialshttps://scigraph.springernature.com/ontologies/product-market-codes/Z12000Surfaces and Interfaces, Thin Filmshttps://scigraph.springernature.com/ontologies/product-market-codes/Z19000Nanoscience.Nanoscience.Nanostructures.Optical materials.ElectronicsMaterials.Materials—Surfaces.Thin films.Nanoscale Science and Technology.Optical and Electronic Materials.Surfaces and Interfaces, Thin Films.546.681Van Tuan Dinhauthttp://id.loc.gov/vocabulary/relators/aut1062189MiAaPQMiAaPQMiAaPQBOOK9910254610003321Charge and Spin Transport in Disordered Graphene-Based Materials2523322UNINA
