The last few years have seen dramatic advances in the growth, fabrication and characterization of low-dimensional materials (such as graphene) and nanostructures (such as those formed from ultrathin films, wires, discs and other "dots"), formed either singly or in spatially periodic arrays. Most studies of these artificially engineered materials have been driven by their potential for device applications that involve smaller and smaller physical dimensions. In particular, the dynamical properties of these materials are of fundamental interest for the devices that involve high-frequency operation and/or switching. Consequently, the different excitations, vibrational, magnetic, optical, electronic, and so on, need to be understood from the perspective of how their properties are modified in finite structures especially on the nanometre length scale due to the presence of surfaces and interfaces. Recently, the patterning of nanoelements, into periodic and other arrays, has become a focus of intense activity, leading for example to photonic crystals and their analogues such as phononic and magnonic crystals where the control of the band gaps in the excitation spectrum is a basis for applications. The nonlinear properties of the excitations are increasingly a topic of interest, as well as the linear dynamics.

This book describes most recent progress in the properties, synthesis, characterization, modelling, and applications of nanomaterials and nanodevices. It begins with the review of the modelling of the structural, electronic and optical properties of low dimensional and nanoscale semiconductors, methodology of synthesis, and characterization of quantum dots and nanowires, with special attention towards Dirac materials, whose electrical conduction and sensing properties far exceed those of silicon-based materials, making them strong competitors. The contributed reviews presented in this book touch on broader issues associated with the environment, as well as energy production and storage, while highlighting important achievements in materials pertinent to the fields of biology and medicine, exhibiting an outstanding confluence of basic physical science with vital human endeavor. The subjects treated in this book are attractive to the broader readership of graduate and advanced undergraduate students in physics, chemistry, biology, and medicine, as well as in electrical, chemical, biological, and mechanical engineering. Seasoned researchers and experts from the semiconductor/device industry also greatly benefit from the book’s treatment of cutting-edge application studies.

Volume 2: Physical Properties of Nanostructured Materials and Their Applications of Nanotechnology: The Physics of Nanomaterials (2-volume set) provides a good overview of the main techniques of the working principles and the type of structures that can be produced with nanomaterials. Specifically, Volume 2 discusses the mechanical, electrical, and optical properties of nanostructures as well as nanomagnetism, spintronics, spin dynamics, as well as a broad range of applications to illustrate how the physical properties of materials can be manipulated to perform very specific functions. Nanotechnology: The Physics of Nanomaterials (2-volume set) is a comprehensive guide to the various aspects of nanophysics. The author’s microscopic approach illustrates how physical principles can be used to understand the basic properties and functioning of low-dimensional systems. It provides an in-depth introduction to the techniques of production and analysis of materials at the nanoscopic level. Much of physics is based on our understanding of solid-state physics. These volumes show how limitations of size can give rise to new physical properties and quantum effects, which can be exploited in new applications and devices. Volume 1: The Physics of Surfaces and Nanofabrication Techniques provides a broad introduction to nanophysics and nanotechnologies, and the importance of low-dimensional and surface physics is discussed indepth. Chapters in Volume 1 covers the large range of physical preparation techniques available for the production of nanomaterials and nanostructuring. Key features: Provides a comprehensive treatment of nanoscience, covering all major areas of the physics involved in nanostructures, including sample preparation techniques, characterization methods, physical principles, and applications Presents an introduction and summary to each chapter, highlighting the principal ideas of each chapter in a concise manner Includes revision problems that will allow students to assess their progress at the end of each chapter Incorporates the author’s 25 years research experience Based on a lecture course the author has given over a period of several years, Nanotechnology: The Physics of Nanomaterials includes the benefit of feedback from students, helping to make the subject matter approachable and appealing to newcomers and students. The volumes will be valuable for courses in nanotechnologies, nanomedicine, nanobiotechnologies and more.

The term low-dimensional systems, which is used in the title of this volume, refers to those systems which contain at least one dimension that is intermediate between those characteristic of atoms/molecules and those of the bulk material. Depending on how many dimensions lay within this range, one generally speaks of quantum wells, quantum wires, and quantum dots. At such an intermediate state, some properties of low-dimensional systems are very different from those of their molecular and bulk counterparts. These properties generally include optical, electronic, and magnetic properties, and all these are partially covered in this book. The book's main thrust is a discussion of the actual state of the art in the broad area of nanotechnology. The initial focus is on the innovative synthesis of nanomaterials and their properties, such as quantum size effects, superparamagnetism, or field emission. These topics lead into the various field-based interactions, including plasmon-magnetic-spin- and exciton coupling. The newer, more sophisticated methods for characterizing nanomaterials are discussed, as well as the methods for possible industrial applications. In general, chemists and physicists, as well as experts on both theory and experiments on nanosized regime structures meet here to discuss the general phenomena underlying their fields of interest from different points of view.

Nowadays, with the improved abilities of computers, molecular modeling has become a powerful technique in computational chemistry with ever-increasing practical interests. At the moment, using effective algorithms along with powerful processors enables us to simulate systems, including thousands of atoms up to several microseconds. However, finding a balance between the computational costs and reliable results still remains a challenge. Two general approaches help us to reveal the behavior of these systems: quantum chemical calculations and molecular mechanics calculations. Quantum mechanics deals with physical phenomena as well as atoms behavior during chemical bonding and falls in the category of modern physics. In this book, two of the most practical quantum mechanics approaches are investigated: density functional theory (DFT) and density-functional tight-binding (DFTB).

This is the first book to systematically review and summarize the recent rapid advances and varied results of multiphysics in nanoscale materials including elastic strain engineering. This book comprises topics on remarkable properties of multiphysics in low-dimensional nanoscale components from first-principles density-functional theory (or tight binding) calculations, which are essential for the nonlinear multiphysics couplings due to quantum mechanical effects. This volume provides a clear point of view and insight into the varied work done in diverse fields and disciplines and promotes a fundamental to state-of-the-art understanding of properties of multiphysics. Because the novelty and complexity of mechanical and multiphysical properties of low-dimensional nanostructures originate from combinations of outer shapes (e.g., films, wires, tubes, and dots) and inner understructures (e.g., grain boundaries, domain walls, vacancies, and impurities), the nanostructures are classified into fundamental elements, and the properties of each element and their interplay are reviewed for systematic, in-depth understanding. This book points out a new direction for multiphysics in nanostructures, which opens the door both to exploiting and to designing novel functionalities at the nanoscale. Readers will be interested in this rapidly expanding multidisciplinary work and will be motivated to enter this promising research area.
