This book combines the proceedings of Symposium Q, Magnetoelectronics-Novel Magnetic Phenomena in Nanostructures, and Symposium R, Advanced Characterization of Artificially Structured Magnetic Materials, both from the 2002 MRS Fall Meeting in Boston. The common focus is on artificially engineered nanostructured magnetic systems. The two symposia address new phenomena in magnetoelectronic applications, their preparation, and advanced methodology for characterization. Interest in nanomagnetism has been catalyzed by advances in two fields of research. 1) Advances in materials synthesis of structures whose length scales transcend magnetic length scales and open the possibility for creating materials with new magnetic properties. Such structures include interfaces, superlattices, tunneling devices, nanostructures, and single-molecule magnets. 2) Advances in sample characterization techniques for nano-magnetism which allow detailed exploration of structure-property relationships in nanostructured magnetic systems. The volume highlights current trends in both fields and offers an outlook for further advances and new capabilities.

Progress in MOS integrated-circuit technology is largely driven by the ability to dimensionally scale the constituent components of individual devices and their associated interconnections. Given a set of materials with fixed properties, this scaling is finite and its predicted limits are rapidly approaching. The International Technology Roadmap for Semiconductors establishes the pace at which this scaling occurs and identifies many of the technological challenges ahead. This volume assembles representatives from the fields of materials science, physics, electrical and chemical engineering to provide an insightful review of current technology and understanding. Specifically, the intent is to discuss materials issues stemming from device scaling to sub-100nm technology nodes. Topics include: high-k characterization; atomic layer deposition; gate metal materials and integration; contacts and ultrashallow junction formation; theory and modeling and crystalline oxides for gate dielectrics.

The MRS Symposium Proceeding series is an internationally recognised reference suitable for researchers and practitioners.

Advances in nanoscale materials processing are taking place at a rapid pace via myriad paths, including lithography, production of nanoparticle assemblies, surface manipulation and many others. Several of the techniques create structures that are three-dimensional or quasi three-dimensional. Even smaller structures intended to be two-dimensional have a 'more' three-dimensional geometry as their two-dimensional feature size and layer thickness become similar. The properties of these denser assemblies are driving different applications in electronics (single-electron devices), optics (photonic crystals and switches) and elsewhere. This 2003 book provides a venue for a productive scientific and technical exchange. The result is a compilation of papers which address fundamental studies, technological advances and novel approaches to developing and processing three-dimensional nanoscale assemblies. Topics include: nanofabrication via lithographic techniques; unconventional fabrication methods of nano-structures; physics, chemistry and modeling of nanostructures; fabrication and properties of 1D nanostructures; fabrication and properties of 3D nanostructures; applications of nanostructures and devices.

The MRS Symposium Proceeding series is an internationally recognised reference suitable for researchers and practitioners. This 2003 volume focuses on experimentally validated multiscale modeling of ductile metals and alloys.

This year's nitride symposium showed the scope of nitride-related advances spanning basic materials physics over process technology to high-performance devices. Progress was reported in bulk growth of GaN and AlN, growth on various substrates and substrate orientations, optical properties of InN, defect and doping analysis of p-doped GaN, and polarization properties. These led to new performance records in visible light emitter technology, i.e., higher efficiency/higher brightness, UV emitters with shorter wavelength, and UV and photo detectors. Advances in the development of nitride-based electronic devices with new heterostructure FET designs for RF power applications, including those on Si substrates and wafer fusion, are also reported. This book captures the exciting developments in this rapidly progressing field. Topics include: epitaxy - devices and defect reduction; defects and characterization; epitaxy - nonpolar orientations and alloys; optical properties; UV emitters and detectors; visible light emitters; electronic devices; characterization of defects and transport; and contacts, processing and p-type nitrides.

This book contains the proceedings of two symposia held at the 2002 MRS Fall Meeting in Boston. Papers from Symposium T, Crystalline Oxides on Semiconductors, bring together experts from different technology areas - high-k gate dielectrics, novel memories, and ferroelectrics, for example - to examine commonality among the fields. These papers offer an overview of the field, highlight interesting experimental results and device ideas, and feature innovative theoretical approaches to understanding these systems. Symposium V, Interfacial Issues for Oxide-Based Electronics, covers a wide range of topics involving the interfaces between electro-optical oxide layers and other materials. Overall, it is clear that a new generation of materials and heterostructures has been enabled by the increasing control of interfacial phenomena. Topics include: epitaxial oxide-silicon heterostructures; ferroelectric thin films on silicon; theory and modeling; crystalline oxides for gate dielectrics; transparent conducting oxides; transparent conducting oxides and oxide growth and properties; field effect devices and gate dielectrics; ferroelectrics, capacitors and sensors; organic devices and interfacial growth issues.

As nanotechnology has developed over the last two decades, some nanostructures, such as nanotubes, nanowires, and nanoparticles, have become very popular. However, recent research has led to the discovery of other, less-common nanoforms, which often serve as building blocks for more complex structures. In an effort to organize the field, the Handbook of Less-Common Nanostructures presents an informal classification based mainly on the less-common nanostructures. A small nanotechnological encyclopedia, this book: Describes a range of little-known nanostructures Offers a unifying vision of the synthesis of nanostructures and the generalization of rare nanoforms Includes downloadable resources with color versions of more than 100 nanostructures Explores the fabrication of rare nanostructures, including modern physical, chemical, and biological synthesis techniques The Handbook of Less-Common Nanostructures discusses a classification system not directly related to the dimensionality and chemical composition of nanostructure-forming compounds or composite. Instead, it is based mainly on the less-common nanostructures. Possessing unusual shapes and high surface areas, these structures are potentially very useful for catalytic, medical, electronic, and many other applications.

A primary driver of progress in nanoscience and technology is the continuing advances in the ability to measure structure, and particularly properties, at spatially localized scales. From the point of view of characterization, it is worth mentioning advances in the interpretation of processes in semiconductors, the ability to observe and manipulate metal, carbon and silicon nanowires and nanodots, and studies in molecular self-assembly. The papers in this book fall into two categories - those addressing classes of characterization techniques that emphasize how the combination of theoretical, experimental, and instrumentational developments lead to new capabilities in nanoscale characterization, and those focused on the use of various spatially localized approaches on a single phenomenon or materials issue. Topics include: characterization with electron optics; novel measurements of nanoscale properties; size-dependent behavior of nanoparticles; biological systems at the nanoscale; processing and properties of nanowires and heterostructures; and local phenomena in materials and microstructures.

Since its inception in the mid-twentieth century, solid-state chemistry has matured within the chemical sciences. In the same way that chemistry itself is considered a central science, solid-state chemistry is central in its many relations to physics, in particular to solid-state physics and also to materials science and engineering. There are few problems in materials science or engineering in which the preparation of the material itself is not a central issue and, more often than not, this will be a solid-state chemical problem. For these reasons, it is not surprising that in the technological development of the last century, solid-state chemistry has grown in importance. It is not only a synthesis science, it is also the science of structures, defects, stoichiometry, and physical chemical properties. Most of these are explored in the book. Topics include: metal-to-insulator transition; porous materials; dielectric materials; nanomaterials; synthesis of materials; films and catalytic materials; CMR materials; thermoelectric materials; dielectrics, catalysts, phosphors, films and properties and synthesis and crystal growth.
