Описание: Recent developments in the technology of silicon nanocrystals and silicon nanostructures, where quantum-size effects are important, are systematically
described including examples of device applications. Due to the strong quantum confinement effect, the material properties are freed from the usual indirect- or direct-bandgap regime,
and the optical, electrical, thermal, and chemical properties of these nanocrystalline and nanostructured semiconductors are drastically changed from those of bulk silicon. In addition to
efficient visible luminescence, various other useful material functions are induced in nanocrystalline silicon and periodic silicon nanostructures.
Some novel devices and
applications, in fields such as photonics (electroluminescence diode, microcavity, and waveguide), electronics (single-electron device, spin transistor, nonvolatile memory, and ballistic
electron emitter), acoustics, and biology, have been developed by the use of these quantum-induced functions in ways different from the conventional scaling principle for ULSI.

Описание: Advanced magnetic nanostructures is an emerging field in magnetism and nanotechnology, but the literature consists of a rich variety of original papers and parts of reviews and books whose scope is comparatively broad. This calls for a book with specific emphasis on state-of-the-art synthetic methods for fabricating, characterizing and theoretically modeling new magnetic nanostructures. This book is intended to provide a comprehensive overview of the present state of the field. Leading researchers world-wide have contributed a survey of their special ties to guide the reader through the exploding literature in nanomagnetic structures. The focus is on deliberately structured nanomagnets. It includes cluster assembled, self-organized and patterned thin films but excludes, for example, multilayered thin films. We target both industrial and academic researchers in magnetism and related areas, such as nanotechnology, materials science, and theoretical solid-state physics.

Описание: Progress in nanoscience is becoming increasingly dependent on simulation and modelling. This is due to a combination of three factors: the reduced size of nano-objects, the increasing power of computers, and the development of new theoretical methods. This book represents the first attempt to provide the theoretical background needed by physicists, engineers and students to simulate nanodevices, semiconductor quantum dots and molecular devices. It presents in a unified way the theoretical concepts, the more recent semi-empirical and ab-initio methods, and their application to experiments. The topics include quantum confinement, dielectric and optical properties, non-radiative processes, defects and impurities, and quantum transport. This guidebook not only provides newcomers with an accessible overview (requiring only basic knowledge of quantum mechanics and solid-state physics) but also provides active researchers with practical simulation tools.

Описание: Provides a general introduction to photovoltaics with a focus on the fundamental physical limits and practicality of assumptions which form the basis for the ensuing discussion of nanostructured approaches to photovoltaics conversion.
Описание: This novel book is the first comprehensive text on Dynamical Mean-Field Theory (DMFT), which has emerged over the past two decades as one of the most
powerful new developments in many-body physics. Written by one of the key researchers in the field, the volume develops the formalism of many-body Green's functions using the
equation of motion approach, which requires an undergraduate solid state physics course and a graduate quantum mechanics course as prerequisites. The DMFT is applied to study
transport in multilayered nanostructures, which is likely to be one of the most prominent applications of nanotechnology in the coming years.
The text is modern in scope
focusing on exact numerical methods rather than the perturbation theory. Formalism is developed first for the bulk and then for the inhomogeneous multilayered systems. The science
behind the metal-insulator transition, electronic charge reconstruction, and superconductivity are thoroughly described.
The book covers complete derivations and
emphasizes how to carry out numerical calculations, including discussions of parallel programing algorithms. Detailed descriptions of the crossover from tunneling to thermally activated
transport, of the properties of Josephson junctions with barriers tuned near the metal-insulator transition, and of thermoelectric coolers and power generators are provided as applications
of the theory.
Описание: This book will discuss advances in the area of functional thin films for sensors and novel concepts for future breakthroughs. The focus will be on guidelines and design rules for sensor systems, interaction between functional thin films and other sensor subsystems, fundamentals behind the intrinsic functionality in sensing thin films and nanostructures, state-of-the-art technologies used to develop sensors today and concrete examples of sensor designs.Coverage of nanoscale thin films for sensors includes the following important topics: Fundamental physics of functional thin films and nanostructures; Synthesis processes of functional thin films; Integration of functional thin films; Applications of functional thin films in sensing.
Описание: Nanocrystalline materials exhibit the outstanding properties and represent a new class of structural materials having a wide range of applications. In particular, there is considerable interest in developing nanocrystalline materials to be used as functional materials in aerospace applications, automotive industry, wear applications, MEMS, etc. The future progress in these high technological applications of nanocrystalline materials crucially depends on development of new methods of their fabrication and understanding of the underlying nano-scale and interface effects causing their unique mechanical properties.
Описание: Ordered porous nanostructures have emerged in the last ten years in different kinds of materials and with different pore diameters and interpore spacing. This book reviews in the first part which kinds of materials exhibit ordered nanopores and what are the physico-chemical reasons for it. In the second part, this book discusses the possible applications from photonic crystals via high-throughput screening to metallic and polymer-nanowire arrays and their use in the case of ferromagnetic wires as high-density magnetic storage medium.This book reviews the most interesting materials on the market concerning self-ordering, including: macroporous silicon, porous alumina, MCM41 and photonic bandgap materials, which is one of the hottest topics in optics and nano-technology in the last five years, according to Science magazine. In computer applications, these structures enable significantly higher storage densities than are possible with thin film media. Moreover, these structures find uses in template fabrication for nanowire-arrays, high-throughput screening, lab-on-a-chip, ULSI circuitry for trenches and capacitors.
Описание: With cutting-edge materials and minute electronic devices being produced by the latest nanoscale fabrication technology, it is essential for scientists and
engineers to rely on first-principles (ab initio) calculation methods to fully understand the electronic configurations and transport properties of nanostructures. It is now imperative to
introduce practical and tractable calculation methods that accurately describe the physics in nanostructures suspended between electrodes. This timely volume addresses novel
methods for calculating electronic transport properties using real-space formalisms free from geometrical restrictions.
The book comprises two parts: The first details the basic
formalism of the real-space finite-difference method and its applications. This provides the theoretical foundation for the second part of the book, whic
presents the methods for calculating the properties of electronic transport through nanostructures sandwiched by semi-infinite electrodes.
