ќписание: In Periodic Nanostructures, the authors demonstrate that structural periodicity in various nanostructures has been proven experimentally. The text covers the coalescence reactions, studied by electronic microscopy, and shows that the nanoworld is continuous, giving rise to zero- (fullerenes), one- (tubules), two-(graphite) and three-(diamond, spongy carbon) dimensional carbon allotropes.The authors explore foam-like carbon structures, which relate to вАШschwarzitesвАЩ, and which represent infinite periodic minimal surfaces of negative curvature. They show that these structures contain polygons (with dimensions larger than hexagons w.r.t. to graphite) that induce this negative curvature. The units of these structures appear as nanotube junctions (produced via an electron beam) that have wide potential molecular electronics applications. Self-assembled supramolecular structures (of various tessellation) and diamond architectures are also proposed. The authors propose that the periodicity of close repeat units of such structures is most evident not only in these formations but also present in all of the carbon allotropes. It is also shown that depending on the lattice tessellation, heteroatom type, and/or doping, metal nanostructures (nanotubes in particular) can display both metallic and semiconductor characteristics. Therefore, their properties can be manipulated by chemical functionalization. The authors therefore suggest that nanostructures have heralded a new generation of nanoscale biological, chemical, and physical devices.The text also provides literature and data on the field of nanostructure periodicity and the authorsвАЩ own results on nanostructure building and energy calculations as well as topological characterization by means of counting polynomials of periodic nanostructures. The aromaticity of various coverings of graphitic structures is also discussed.This book is aimed at scientists working in the field of nanoscience and nanotechnology, Ph.D. and MSc. degree students, and others interested in the amazing nanoarchitectures that could inspire the cities of the future.
ќписание: 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.
ќписание: 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.
ќписание: 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.
ќписание: 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.
ќписание: 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.
ќписание: Nanotechnology is the buzzword these days. This book provides a broad overview of nanotechnology as applied to contemporary electronics and photonics.
The areas of application described are typical of what originally set off the nanotechnology revolution.
An account of original research contributions from researchers all over
the world, the book is extremely valuable for gaining an understanding of the latest developments in applied nanotechnology. Clearly structured and readable, the book is useful for both
students and researchers alike: students can learn about the various aspects of nanotechnology and professional researchers can update themselves on the new developments in this
dynamic field.The book covers nanoscale materials and devices for both electronics and optical technologies. The emphasis throughout is on experimental methods rather than
The material will provide food for thought for researchers and research students keen to develop new technologies at the ultra-small scale and to open
up new avenues for research.
ќписание: This comprehensive volume presents invited reviews and short notes with exciting new results obtained in fabrication study and application of nanostructures,
which promise a new generation of electronic and optoelectronic devices. The rapid progress in nanoelectronics and optoelectronics, molecular electronics and spintronics,
nanotechnology and quantum processing of information are covered.

ќписание: The main theme of this book is the exploration the underlying physical laws that permit the fabrication of nanometer-scale structures. As researchers attempt to fabricate nanometer-scale structures which do not exist per se, they must still employ the natural laws to fabricate them through processes such as self-assembly. This book will find service both as a reference work for researchers and as a comprehensive didactical text for graduate students.
