Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the first systematic electron transport investigation of rhombohedral graphite (RG) films and thus lies at the interface of graphene physics, vdW heterostructure devices and topological matter. Electron transport investigation into the rhombohedral phase of graphite was limited to a few layers of graphene due to the competing hexagonal phase being more abundant. This work reports that in exfoliated natural graphite films, rhombohedral domains of up to 50 layers can be found. In the low energy limit, these domains behave as an N-layer generalisation of graphene. Moreover, being a potential alternative to twisted bilayer graphene systems, RG films show a spontaneous metal-insulator transition, with characteristic symmetry properties that could be described by mean-field theory where superconductivity is also predicted in these low energy bands. A nodal-line semimetal in the bulk limit, RG thin films are a 3D generalisation of the simplest topological insulator model: the Su-Schrieffer-Heeger chain. Similar to the more usual topological insulators, RG films exhibit parallel conduction of bulk states, which undergo three-dimensional quantum transport that reflects bulk topology.

Download or read book Graphite Intercalation Compounds II written by Hartmut Zabel and published by Springer Science & Business Media. This book was released on 2013-03-07 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research on graphite intercalation compounds often acts as a forerunner for research in other sciences. For instance, the concept of staging, which is fundamental to graphite intercalation compounds, is also relevant to surface science in connection with adsorbates on metal surfaces and to high-temperature superconducting oxide layer materials. Phonon-folding and mode-splitting effects are not only basic to graphite intercalation compounds but also to polytypical systems such as supercon ductors, superlattices, and metal and semiconductor superlattices. Charge transfer effects playa tremendously important role in many areas, and they can be most easily and fundamentally studied with intercalated graphite. This list could be augmented with many more examples. The important message, however, is that graphite inter calation compounds represent a class of materials that not only can be used for testing a variety of condensed-matter concepts, but also stimulates new ideas and approaches. This volume is the second of a two-volume set. The first volume addressed the structural and dynamical aspects of graphite intercalation compounds, together with the chemistry and intercalation of new compounds. This second volume provides an up-to-date status report from expert researchers on the transport, magnetic, elec tronic and optical properties ofthis unique class of materials. The band-structure cal culations of the various donor and acceptor compounds are discussed in depth, and detailed reviews are provided ofthe experimental verification ofthe electronic struc ture in terms of their photoemission spectra and optical properties.

Download or read book Chemical Modifications Of Graphene like Materials written by Nguyen Thanh Tien and published by World Scientific. This book was released on 2023-12-27 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: Graphene-like materials have attracted considerable interest in the fields of condensed-matter physics, chemistry, and materials science due to their interesting properties as well as the promise of a broad range of applications in energy storage, electronic, optoelectronic, and photonic devices.The contents present the diverse phenomena under development in the grand quasiparticle framework through the first-principles calculations. The critical mechanisms, the orbital hybridizations and spin configurations of graphene-like materials through the chemical adsorptions, intercalations, substitutions, decorations, and heterojunctions, are taken into account. Specifically, the hydrogen-, oxygen-, transition-metal- and rare-earth-dependent compounds are thoroughly explored for the unusual spin distributions. The developed theoretical framework yields concise physical, chemical, and material pictures. The delicate evaluations are thoroughly conducted on the optimal lattices, the atom- and spin-dominated energy bands, the orbital-dependent sub-envelope functions, the spatial charge distributions, the atom- orbital- and spin-projected density of states, the spin densities, the magnetic moments, and the rich optical excitations. All consistent quantities are successfully identified by the multi-orbital hybridizations in various chemical bonds and guest- and host-induced spin configurations.The scope of the book is sufficiently broad and deep in terms of the geometric, electronic, magnetic, and optical properties of 3D, 2D, 1D, and 0D graphene-like materials with different kinds of chemical modifications. How to evaluate and analyze the first-principles results is discussed in detail. The development of the theoretical framework, which can present the diversified physical, chemical, and material phenomena, is obviously illustrated for each unusual condensed-matter system. To achieve concise physical and chemical pictures, the direct and close combinations of the numerical simulations and the phenomenological models are made frequently available via thorough discussions. It provides an obvious strategy for the theoretical framework, very useful for science and engineering communities.

Download or read book Diverse Quantization Phenomena in Layered Materials written by Chiun-Yan Lin and published by CRC Press. This book was released on 2019-12-06 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph offers a comprehensive overview of diverse quantization phenomena in layered materials, covering current mainstream experimental and theoretical research studies, and presenting essential properties of layered materials along with a wealth of figures. This book illustrates commonly used synthesis methods of these 2D materials and compares the calculated results and experimental measurements, including novel features not yet reported. The book also discusses experimental measurements of magnetic quantization, theoretical modeling for studying systems and covers diversified magneto-electronic properties, magneto-optical selection rules, unusual quantum Hall conductivities, and single- and many-particle magneto-Coulomb excitations. Rich and unique behaviors are clearly revealed in few-layer graphene systems with distinct stacking configuration, stacking-modulated structures, silicon-doped lattices, bilayer silicene/germanene systems with the bottom-top and bottom-bottom buckling structures, monolayer and bilayer phosphorene systems, and quantum topological insulators. The generalized tight-binding model, the static and dynamic Kubo formulas, and the random-phase approximation are developed/modified to thoroughly explore the fundamental properties and propose the concise physical pictures. Different high-resolution experimental measurements are discussed in detail, and they are consistent with the theoretical predictions. Aimed at readers working in materials science, physics, and engineering this book should be useful for potential applications in energy storage, electronic devices, and optoelectronic devices.
