about

Graphene is the first example of two-dimensional materials and is the most important growth area of contemporary research. It forms the basis for new nanoelectronic applications. Graphene, which comprises field-effect structures, has remarkable physical properties.

This book focuses on practical applications determined by the unique properties of graphene. Basic concepts are elucidated by end-of-chapter problems, the answers to which are provided in the accompanying solutions manual. The mechanisms of electric and thermal transport in the gated graphene, interface phenomena, quantum dots, non-equilibrium states, scattering and dissipation, as well as coherent transport in graphene junctions are considered in detail in the book. Detailed analyses and comparison between theory and experiments is complemented with a variety of practical examples.

The book has evolved from the author's own research experience and from his interaction with other scientists at tertiary institutions and is targeted at a wide audience ranging from graduate students and postdoctoral fellows to mature researchers and industrial engineers.

Editorial Reviews

"Graphene: Fundamentals, Devices, and Applications provides a comprehensive textbook, primarily focused on graphene but also containing up-to-date coverage of carbon nanotubes, and even an introduction to few-layered transition metal dichalcogenides. Each of the 11 chapters ends with a problem set and an extensive list of references. Many examples of device applications are given in each chapter, thereby making the book attractive to practicing engineers and engineering students." ¿Prof. Mildred Dresselhaus, Massachusetts Institute of Technology, USA "This book is the most advanced introduction to a fascinating world of two-dimensional materials. Detailed and self-contained description of electric, thermal, and thermoelectric properties of graphene and graphene nanostructures is a valuable resource for researchers in physics, materials science, nanotechnologies, and sensing. Accessible presentation of the most complicated phenomena and interesting original problems will be appreciated by graduate students." ¿Prof. Vladimir Mitin, The State University of New York, USA "This is a long-awaited monograph that provides a direct link from the unique energy spectra, including the chiral properties, thermal and electric transport, as well as vibrational, interface, scattering, and dissipation phenomena in both ideal and dirty graphene, to their remarkable possible applications. Graphene nanocoolers and cogenerators of electricity are splendid examples of such novel applications in thermoelectricity. The miraculous potentialities of graphene-quantum-dot-based structures as THz detectors are supported by a big number of both theoretical analyses and experimental observations. I strongly recommend this book to all who are interested in the most recent advances in the fascinating field of monolayered nanostructures." ¿Prof. Vladimir M. Fomin, Leibniz Institute for Solid State and Materials Research (IFW), Germany
