Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this symposium was to bring together researchers from a broad range of disciplines to discuss the challenges facing the implementation of an affordable tunable RF and microwave device technology. Low cost, tunable, microwave devices will have a tremendous impact on a variety of commercial and military systems, including, but not limited to, tunable band-select filters for wireless communications, phase shifters and true time delay devices for electronic scanning antennas, tunable radiating structures for frequency hopping, and tunable transformers to reduce RF impedance mismatch. The papers of this proceedings discuss a wide range of topics from materials issues through devices and even a system level demonstration of electronic beam steering. Specific materials issues discussed are: new tunable materials; issues of tunability, preparation and optimization of bulk and thin film properties; materials, surface, and interface characterization; evaluation of material loss and loss mechanisms; effects of microstructure; and temperature stability. At the device level, phase shifters are discussed and a new device concept for variable true time delay versus phase shift is introduced. At the system level, a paraelectric lens is used to demonstrate electronic beam steering of an antenna at 10 GHz with about 2 dB of loss.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the deliberate introduction and manipulation of defects and impurities in order to engineer desired properties in semiconductor materials and devices. In view of current exciting developments in wide-bandgap semiconductors like GaN for blue light emission, as well as high-speed and high-temperature electronics, dopant and defect issues relevant to these materials are addressed. Also featured are semiconductor nanocavities and nano-structures, with emphasis on the formation and impact of vacancy-type defects. Defect reaction problems pertaining to impurity gettering, precipitation and hydrogen passivation are specific examples of defect engineering that improve the electronic quality of the material. A number of papers also deal with characterization techniques needed to study and to identify defects in materials and device structures. Finally, papers also address issues such as interface control and passivation, application of ion implantation, plasma treatment and rapid thermal processing for creating/activating/suppressing trap levels, and device applications.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of two symposia held at the 2002 MRS Spring Meeting in San Francisco. Molecular imprinting (MI) technology has attracted much attention and enjoyed tremendous development over the past decade. MI technology enables the preparation of materials with host sites that recognize specific guest molecules, analogous to the "lock-and-key" paradigm of antibodies and enzymes. Advantages of molecularly imprinted materials include: a degree of specificity approaching that of antibodies but with much greater temporal and thermal stability; rapid development because precise molecular design and chemical synthesis are unnecessary; and wide applicability because materials may be imprinted with almost any shape-persistent analyte of interest. Papers from Symposium M, "Molecularly Imprinted Materials, focus primarily on the fabrication of functional materials and devices based on MI materials. Studies are presented not only by experts in MI, but more importantly, by materials scientists integrating molecular imprinting with cutting-edge techniques in microfabrication and nanotechnology.

This book was released on 1999 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proceedings contains papers presented at Symposium KK, "Materials Issues for Tunable RF and Microwave Devices," held November 30-December 2 at the 1999 MRS Fall Meeting in Boston, Massachusetts. Electric or magnetic tunability of RF and microwave devices is desirable for a variety of civilian and military applications. In recent years, there have been tremendous advances in thin-film processing, in particular the metal-oxide thin films. Consequently, it has been recognized that the integration of nonlinear-dielectric, ferrite, colossal magnetoresistive (CMR), and superconductor materials could revolutionize tunable devices by providing new capabilities while significantly reducing size and cost. Some of the crucial issues facing the tunable RF and microwave device technology concern the material properties, in particular the loss in thin films of the tunable materials. Extensive efforts are being devoted to understand the tuning and loss mechanisms, improve thin-film processing and characterization, develop new materials, and design novel device concepts. The papers contained in this volume are a reflection of the work currently in progress in this exciting area. They range from electric-field to magnetic-field tuning, from devices to materials, and from fundamental understanding to materials characterization. The authors come from different materials communities: nonlinear dielectric, ferrite, colossal magnetoresistive (CMR), semiconductors, superconductivity, and device engineering, etc. We hope that this volume will serve as an up-to-date reference for the researchers inside and outside the field of tunable RF and microwave devices, and thus contribute to new breakthroughs in the basic and applied research in this rapidly expanding field.

This book was released on 2003-06-25 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: Defects such as dislocations, antiphase domains and grain boundaries, interstitials/substitutionals, and vacancies affect many physical and mechanical properties of ordered intermetallics. As a result, they often play a decisive role in determining the macroscopic behavior of not just structural intermetallics but also 'functional' intermetallics such as shape memory alloys and hydrogen storage materials. This book follows in the general tradition of the highly successful series of MRS symposia titled High-Temperature Ordered Intermetallic Alloys. However, it also represents a significant departure from its predecessors: it includes papers on functional intermetallics in addition to papers on structural intermetallics; and focuses on defects and how they affect various properties of interest in structural and functional intermetallics. Roughly 30 percent of the papers in the book are on functional intermetallics, including materials for hydrogen storage, magnetic, and shape memory applications. The remaining papers deal with structural intermetallics, including the still active areas of nickel-, iron-, and titanium-aluminides, as well as the newer materials for ultrahigh-temperature applications.
