"The papers compiled in this volume were presented in Symposium W, 'Morphological and Compositional Evolution of Thin Films, ' held December 2-5 at the 2002 MRS Fall Meeting in Boston Massachusetts. They are organized in the order that they were presented."--P. xiii.
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.
This book discusses current techniques and instrumentation for cluster chemistry. It addresses both the experimental and theoretical aspects of gas-phase metal cluster reactivities, especially those pertaining to pollution removal, energetic reactions and corrosion and anticorrosion. These metal cluster systems have attracted enormous interest as they display a completely new class of physical, chemical, electronic, magnetic and catalytic properties. As these properties change with size and composition, it can thus be understood how their nature evolves from atoms to bulk solids. The book offers readers a basic understanding of the structural chemistry and reactivity of metal clusters in both gas-phase and wet chemistry. Further, the lessons they learn here regarding metal cluster chemistry will prepare researchers for the study of condensed phase dynamics that pertain to wet chemical synthesis, soft-landing deposition and cluster assembly.
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.
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.
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.
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.
