Book Description
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.

Book Description
Advances in silicon carbide materials, processing and device design have recently resulted in implementation of SiC-based electronic systems and offer great promise in high-voltage, high-temperature and high-frequency applications. This volume focuses on new developments in basic science of SiC materials as well as rapidly maturing device technologies. The challenges in this field include understanding and decreasing defect densities in bulk SiC crystals, controlling morphology and residual impurities in epilayers, optimization of implant activation and oxide-SiC interfaces, and developing novel device structures. This book brings together the crystal growers, physicists and device experts needed to continue the rapid pace of silicon-carbide-based technology. Topics include: epitaxial growth; characterization/defects; MOS technology; SiC processing and devices.

Book Description
The objective of this 2003 volume from the Materials Research Society is twofold - to provide an overview of advances in membrane science and technology and to enhance communication among membrane researchers from a variety of disciplines including chemistry, biology, biotechnology, chemical engineering and materials science. Membranes can be used for inert or reactive separations in a variety of fields including gas purification, water treatment, energy storage and conversion, bio-technology and biomedicine. The book brings together scientists involved in the entire spectrum of modern approaches to membrane science and technology to address synthesis, characterization and transport properties and their use in established and emerging applications. Topics include: membrane synthesis and preparation; surface modification and additives; hybrid and composite membranes; membrane characterization; transport phenomena in membranes; charged membranes and ion transfer; gas permeation and separation; pervaporation and vapor permeation; dense membranes for hydrogen separation; applications in biotechnology and biomedicine; and membrane R&D for industrial and emerging applications.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
The field of organic semiconductors has seen much development in the past years. Displays based on light-emitting diodes made of small organic molecules as well as polymers, have recently been commercialized. Other applications, such as electronic circuits for tagging, efficient photovoltaic devices and biosensors, have already been demonstrated. This volume brings together a "wish list" of leading researchers in the fields of chemistry, physics and technology of organic devices. Novel device concepts such as charge-generation layers, metal complexes and the use of heterojunctions are presented and should lead to further improvement in the efficiency of organic light-emitting diodes. In the field of organic transistors, major progress is reported on the charge-transport properties of organic semiconductors; mobilities up to 5cm2/Vs are reported for pentacene-based transistors. High mobility n-type materials, which enable the development of ambipolar organic electronic circuits, are also discussed. And new approaches to fully printable displays on substrates, such as textiles and paper, are presented. These may lead the way to new applications of organic optoelectronic devices.
