Introduction to Graphene-Based Nanomaterials Beginning with an introduction to carbon-based nanomaterials, their electronic properties, and general concepts in quantum transport, this detailed primer describes the most effective theoretical and computational methods and tools for simulating the electronic structure and transport properties of graphene-based systems. Transport concepts are clearly presented through simple models, enabling comparison with analytical treatments, and multiscale quantum transport methodologies are introduced and developed in a straightforward way, demonstrating a range of methods for tackling the modeling of defects and impurities in more complex graphene-based materials. The authors also discuss the practical applications of this revolutionary nanomaterial, contemporary challenges in theory and simulation, and long-term perspectives. Containing numerous problems for solution, real-life examples of current research, and accompanied online by further exercises, solutions, and computational codes, this is the perfect introductory resource for graduate students and researchers in nanoscience and nanotechnology, condensed matter physics, materials science, and nanoelectronics. Luis E. F. Foa Torres is a Researcher at the Argentine National Council for Science and Technology (CONICET) and an Adjoint Professor at the National University of C´ordoba, Argentina, specializing in quantum transport with emphasis on inelastic effects and driven systems. Stephan Roche is an ICREA Research Professor at the Catalan Institute of Nanoscience and Nanotechnology (ICN2), where he is Head of the Theoretical and Computational Nanoscience Group, focusing on quantum transport phenomena in materials such as graphene. Jean-Christophe Charlier is a Professor of Physics at the University of Louvain, Belgium, whose interests include condensed matter physics and nanosciences. His main scientific expertise focuses on first-principles computer modeling for investigating carbon-based nanomaterials. Torres, Roche, and Charlier have written a very attractive book on graphene-based materials that takes a reader or student with no prior exposure to this topic to a level where he or she can carry out research at a high level and work in this area professionally, assuming a standard background of a condensed matter physics graduate student. The material is nicely organized into chapters which can be subdivided into daily learning segments and with problem sets that could be helpful for either formal course presentation or self study. Four appendices with more detailed presentations allow readers to develop the skills needed for using and extending present knowledge to advancing the science of few-layered materials or for developing applications based on these materials. All in all I would expect this to become a popular text for present and future researchers who will be active in the present decade, advancing science and launching technological innovation. Mildred Dresselhaus, Massachusetts Institute of Technology This book covers the fundamental aspects of graphene, starting from the very beginning. By reading this book, most basic subjects on graphene and some special theoretical methods can be understood at a high level. Starting with the current status of graphene science, the authors proceed to a self-contained description of the electronic structure of graphene, then an especially detailed description of the transport properties of graphene, such as back scattering, Klein tunnelling, quantum dots, Landau levels etc., based on the authors’ work. Methods introduced to investigate these subjects range from the tight binding method to ab initio calculations, so that the readers can select their preferred method, and the appendices contain useful mathematical explanations for these methods. Thus, without reading the other textbooks, the reader can underst
