Wallbank1st ed. 2014.Cham :Springer International Publishing :Imprint: Springer,2014.1 online resource (101 p.)Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Description based upon print version of record.1-322-13686-6 3-319-07721-X Includes bibliographical references at the end of each chapters.Monolayer Graphene on a hBN Underlay -- Optical Absorption in Graphene-hBN Heterostructures -- Fractal Spectrum of Magnetic Minibands in Graphene-hBN Heterostructures -- Experimental Realisation of the Graphene-hBN Heterostructure -- Bilayer Graphene on hBN -- Monolayer Graphene with Almost Commensurate √3 x √3 Hexagonal Crystals -- Resonant Tunnelling in Graphene-Insulator-Graphene Heterostructures.The last decade has witnessed the discovery of, and dramatic progress in understanding the physics of graphene and related two-dimensional materials. The development of methods for manufacturing and aligning high-quality two-dimensional crystals has facilitated the creation of a new generation of materials: the heterostructures of graphene with hexagonal crystals, in which the graphene electrons acquire new, qualitatively different properties. This thesis provides a comprehensive theoretical framework in which to understand these heterostructures, based on the tight binding model, perturbation theory, group theory and the concept of the moire superlattice (all of which are elucidated). It explains how graphene heterostructures provide new opportunities for tailoring band structure, such as creating additional Dirac points or opening band gaps, and how they manifest themselves in transport measurements, optical absorption spectra and the fractal Hofstadter spectra. Also considered are the heterostructures of bilayer graphene and resonant tunneling in aligned graphene/insulator/graphene devices.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Surfaces (Physics)Interfaces (Physical sciences)Thin filmsOptical materialsElectronicsMaterialsSpectrum analysisMicroscopyMaterials—SurfacesSurface and Interface Science, Thin Filmshttps://scigraph.springernature.com/ontologies/product-market-codes/P25160Optical and Electronic Materialshttps://scigraph.springernature.com/ontologies/product-market-codes/Z12000Spectroscopy and Microscopyhttps://scigraph.springernature.com/ontologies/product-market-codes/P31090Surfaces and Interfaces, Thin Filmshttps://scigraph.springernature.com/ontologies/product-market-codes/Z19000Surfaces (Physics)Interfaces (Physical sciences)Thin films.Optical materials.ElectronicsMaterials.Spectrum analysis.Microscopy.Materials—Surfaces.Surface and Interface Science, Thin Films.Optical and Electronic Materials.Spectroscopy and Microscopy.Surfaces and Interfaces, Thin Films.546.68142Wallbank John Rauthttp://id.loc.gov/vocabulary/relators/aut791861MiAaPQMiAaPQMiAaPQBOOK9910300382003321Electronic Properties of Graphene Heterostructures with Hexagonal Crystals1770510UNINA
