Available in PDF, EPUB and Kindle. Book excerpt: Under this grant a study was carried out of the electronic and optical properties and modeling of intercalated graphite. A major contribution of this work has been the formulation of a model for the electronic structure, applicable to compounds of arbitrary stage and intercalant. The results of this model have been applied to the interpretation of Fermi surface and magnetoreflection measurements also carried out under this grant. These measurements thus provide detailed information on the effect of intercalation on the electronic structure and on the Fermi surfaces of intercalated graphite. Results on infrared spectroscopy of intercalated graphite provide information on the lattice mode structure, complementing the findings on the electronic structure. The use of Raman spectroscopy to study adsorbed species on graphite surfaces is demonstrated. (Author).

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.

Available in PDF, EPUB and Kindle. Book excerpt: The progress of materials science depends on the development of novel materials and the development of novel experimental techniques. The research on graphite intercalation compounds combines both aspects: new compounds with strikingly new and anisotropic properties have been synthesized and analyzed during the past couple of years by means of state-of-the-art experimental methods. At the same time, the preparation of the compounds already known has improved con siderably, giving increased reliability and reproducibility of the experimental results. The high quality experimental data now available have stimulated theo retical work. Moreover, the theoretical work has had a great impact on further experimental studies, with the effect of a much improved understanding of this class of materials. This volume is dedicated to a thorough description of all relevant experimen tal and theoretical aspects of the structural and dynamical properties of graphite intercalation compounds. Because of the large number of topics, a second vol ume, which is now in preparation, will follow and will treat the electronic, transport, magnetic, and optical properties. The second volume will also contain a chapter on applications of graphite intercalation compounds. There have been a number of reviews written on selected aspects of these compounds in various journals and conference proceedings during the last couple of years, but this is the first comprehensive review since the thorough overview provided by M.S. Dresselhaus and G. Dresselhaus appeared ten years ago.

Available in PDF, EPUB and Kindle. Book excerpt: Under this contract a study has been carried out on the electronic, lattice, magnetic, structural, and thermal transport properties of intercalated graphite, including the modeling of these properties. The research program being carried out under this grant has been directed toward gaining an increased and fundamental understanding of the properties of graphite intercalation compounds in order to be able to produce better materials with more controlled physical properties. By using diverse experimental techniques it is possible to correlate and interrelate the electronic, lattice, structural, magnetic and thermal transport properties of intercalated graphite and to interpret the dependence of these properties on the stage of the intercalation compound. During the two year period of this contract major advances have been made in each of these areas. Particularly noteworthy is the use of high resolution electron microscopy to monitor the c-axis and in-plane ordering on an atomic scale. Using single crystal Kish graphite host material, we have found evidence for large regions of defect-free single phase intercalant superlattices with dimensions of at least one order of magnitude greater than expected on the basis of previous work. A major advance has been made in the use of high resolution x-ray scattering to study structural phase transitions in the graphite-bromine system. Work on superconducting compounds has been initiated.

Book excerpt: This book reflects the current status of theoretical and experimental research of graphene based nanostructures, in particular quantum dots, at a level accessible to young researchers, graduate students, experimentalists and theorists. It presents the current state of research of graphene quantum dots, a single or few monolayer thick islands of graphene. It introduces the reader to the electronic and optical properties of graphite, intercalated graphite and graphene, including Dirac fermions, Berry's phase associated with sublattices and valley degeneracy, covers single particle properties of graphene quantum dots, electron-electron interaction, magnetic properties and optical properties of gated graphene nanostructures. The electronic, optical and magnetic properties of the graphene quantum dots as a function of size, shape, type of edge and carrier density are considered. Special attention is paid to the understanding of edges and the emergence of edge states for zigzag edges. Atomistic tight binding and effective mass approaches to single particle calculations are performed. Furthermore, the theoretical and numerical treatment of electron-electron interactions at the mean-field, HF, DFT and configuration-interaction level is described in detail.
