For a long time, I have wished to systematically summarize various dynamic theories associated with quantitative electron micros­ copy and their applications in simulations of electron diffraction patterns and images. This book assumes that readers have some preknowledge of electron microscopy, electron diffraction, and quantum mechanics.

Nanostructures refer to materials that have relevant dimensions on the nanometer length scales and reside in the mesoscopic regime between isolated atoms and molecules in bulk matter. These materials have unique physical properties that are distinctly different from bulk materials. This title provides systematic coverage of basic nanomaterials science including materials assembly and synthesis, characterization, and application. Aimed at both beginners and experts, it balances the chemistry aspects of nanomaterials with physical principles. It also highlights nanomaterial-based architectures including assembled or self-assembled systems. Filled with in-depth discussion of important applications of nano-architectures as well as potential applications ranging from physical to chemical and biological systems, the book should prove a useful reference or text for scientists involved with nanostructures.

Nanowires, nanobelts, nanoribbons, nanorods ..., are a new class of quasi-one- dimensional materials that have been attracting a great research interest in the last few years. These non-carbon based materials have been demonstrated to exhibit superior electrical, optical, mechanical and thermal properties, and can be used as fundamen- tal building blocks for nano-scale science and technology, ranging from chemical and biological sensors, field effect transistors to logic circuits. Nanocircuits built using semiconductor nanowires demonstrated were declared a "breakthrough in science" by Science magazine in 2001. Nature magazine recently published a report claiming that "Nanowires, nanorods, nanowhiskers, it does not matter what you call them, they are the hottest property in nanotechnology" (Nature 419 (2002) 553). There is no doubt that nanowire based quasi-one-dimensional materials will be the new focal point of research in the next decades.Volume 1: Metal and Semiconductor Nanowires covers a wide range of mate- rials systems, from noble metals (such as Au, Ag, Cu), single element semiconductors (such as Si and Ge), compound semiconductors (such as lnP, CdS and GaAs as well as heterostructures), nitrides (such as GaN and SiN ) to carbides (such as SiC). The 3 4 of this volume is to cover the synthesis, properties and device applications objective of nanowires based on metal and semiconductor materials. The volume starts with a review on novel electronic and optical nanodevices, nanosensors and logic circuits that have been built using individual nanowires as building blocks.

Scanning electron microscopy (SEM) can be exploited not only for nanomaterials characterization but also integrated with new technologies for in-situ nanomaterials engineering and manipulation. Scanning Microscopy for Nanotechnology addresses the rapid development of these techniques for nanotechnology, in both technique and application chapters by leading practitioners. The book covers topics including nanomaterials imaging, X-ray microanalysis, high-resolution SEM, low kV SEM, cryo-SEM, as well as new techniques such as electron back scatter diffraction (EBSD) and scanning transmission electron microscopy (STEM). Fabrication techniques integrated with SEM, such as e-beam nanolithography, nanomanipulation, and focused ion beam nanofabrication, are major new dimensions for SEM application. Application areas include the study of nanoparticles, nanowires and nanotubes, three-dimensional nanostructures, quantum dots, magnetic nanomaterials, photonic structures, and bio-inspired nanomaterials. This book will appeal not only to a broad spectrum of nanomaterials researchers, but also to SEM development specialists.

In this book the theories, techniques and applications of reflection electron microscopy (REM), reflection high-energy electron diffraction (RHEED) and reflection electron energy-loss spectroscopy (REELS) are comprehensively reviewed for the first time. The book is divided into three parts: diffraction, imaging and spectroscopy. The text is written to combine basic techniques with special applications, theories with experiments, and the basic physics with materials science, so that a full picture of RHEED and REM emerges. An entirely self-contained study, the book contains much invaluable reference material, including FORTRAN source codes for calculating crystal structures data and electron energy loss spectra in different scattering geometries. This and many other features make the book an important and timely addition to the materials science literature.

Research in carbon nanotubes has reached a horizon that is impacting a variety of fields, such as nanoelectronics, flat panel display, composite materials, sensors, nanodevices and novel instrumentation. The unique structures of the nanotubes result in numerous superior physical and chemical properties, such as the strongest mechanical strength and the highest thermal conductivity, room temperature ballistic quantum conductance, electromechanical coupling, and super surface functionality. Among the various analytical techniques, high-resolution transmission electron microscopy (HRTEM) has played a key role in the discovery and characterization of carbon nanotubes. It may be claimed that carbon nanotubes might not have been discovered without using HRTEM. There is a great need of a book that addresses specifically the theory, techniques and application of electron microscopy and associated techniques for nanotube research. The objective of this book is to fill this gap.

Nanotechnology is a field that has and will have substantial intrinsic merit to new technology advancement and to the world economy and quality of life. Nanostructure is concerned with materials and systems whose structures and components exhibit novel physical, chemical and biological properties due to their small size. The aim is to exploit these properties by gaining control of structures and devices at atomic, molecular, and supra-molecular levels and to learn to efficiently manufacture and use these devices. The potential of this technology is almost beyond comprehension and may include applications such as systems that conduct electricity without loss, materials with orders of magnitude more strength than steel at only a small fraction of the weight, devices that store information comparable in size to the information contained in the Library of Congress so small as to fit into in a shirt pocket, and effective treatments and cures for many diseases. Microscopy in Nanotechnology aims to provide an overview of the basics and applications of various microscopy techniques for nanotechnology.The attraction of such book is evident, since microscopy serves as the "eye" and "hand" of studying nanostructured materials. The structure-composition-processing-property relationships for these sub 100 nm-sized materials can only be understood by employing an array of modern microscopy and microanalysis tools. This book will highlight various microcopy techniques and their applications in this fast-growing field. Topics to be covered will include the following:

Devices built from three-dimensional nanoarchitectures offer a number of advantages over those based on thin-film technology, such as larger surface area to enhance the sensitivity of sensors, to collect more sunlight to improve the efficiency of solar cells, and to supply higher density emitters for increased resolution in flat panel displays. Three-dimensional nanoscale assembly has already been used to generate many prototypes of devices and sensors, including piezoelectric nanogenerators based on ZnO nanowire arrays, photovoltaic devices based on silicon nanowire array p-n junctions, and highly sensitive gas sensors based on metal oxide nanowire arrays among others. Three-Dimensional Nanoarchitectures: Designing Next-Generation Devices describes state-of-the-art synthesis, integration, and design strategies used to create three-dimensional nanoarchitectures for functional nanodevice applications. With a focus on synthesis and fabrication methods for three-dimensional nanostructure assembly and construction, coverage includes resonators, nanophotonics, sensors, supercapacitors, solar cells, and more. This book is an essential reference for a broad audience of researchers in materials science, chemistry, physics, and electrical engineering who want the latest information on synthesis routes and assembly methods. Schematics of device integration and mechanisms as well as plots of measurement data are included.
