The MRS Symposium Proceeding series is an internationally recognised reference suitable for researchers and practitioners. This volume was first published in 1999.
Controlling the properties of materials by modifying their composition and by manipulating the arrangement of atoms and molecules is a dream that can be achieved by nanotechnology. As one of the fastest developing and innovative -- as well as well-funded -- fields in science, nanotechnology has already significantly changed the research landscape in chemistry, materials science, and physics, with numerous applications in consumer products, such as sunscreens and water-repellent clothes. It is also thanks to this multidisciplinary field that flat panel displays, highly efficient solar cells, and new biological imaging techniques have become reality. This second, enlarged edition has been fully updated to address the rapid progress made within this field in recent years. Internationally recognized experts provide comprehensive, first-hand information, resulting in an overview of the entire nano-micro world. In so doing, they cover aspects of funding and commercialization, the manufacture and future applications of nanomaterials, the fundamentals of nanostructures leading to macroscale objects as well as the ongoing miniaturization toward the nanoscale domain. Along the way, the authors explain the effects occurring at the nanoscale and the nanotechnological characterization techniques. An additional topic on the role of nanotechnology in energy and mobility covers the challenge of developing materials and devices, such as electrodes and membrane materials for fuel cells and catalysts for sustainable transportation. Also new to this edition are the latest figures for funding, investments, and commercialization prospects, as well as recent research programs and organizations.
Liquid crystal (LC) materials and devices play a central role in numerous established and emerging technologies. This book focuses on several large areas of research including polymer-dispersed liquid crystal technology and twisted smectic materials and applications, as well as nontraditional LC materials and applications. Various aspects of liquid crystal composite technology are featured. Of note is the work concentrating on the use of holography to imprint information into thin films of these systems. Three different approaches for employing holography with liquid crystal materials are discussed. In the ferroelectric liquid crystal arena, the intricacies of different chiral smectic-C architectures are described using detailed X-ray structural experiments on freestanding films. The differences between a molecule and a phase are explored. A number of nondisplay applications using this class of materials are presented and include topics such as adaptive optics, real-time holography and fiber-to-fiber interconnects. Also discussed are glass-forming liquid crystalline films and their ability to polarize photoluminescent emission, their utility in the fabrication of mid-wavelength infrared polarizers, and their utility in the fabrication of bistable electro-optical elements and broadband reflectors.
The field of organic optical materials is rapidly growing, and advances are being made both in attaining a deeper understanding of device phenomena and in designing improved materials for thin films, fibers and waveguides. This book offers an interdisciplinary discussion of research on electronic and photonic devices made with organic and polymeric materials. The 1999 MRS Spring Meeting was highlighted by several major advances in fields ranging from nonlinear absorbers and electro-optic polymers, to photorefractive polymers, organic transistors and electroluminescent materials and devices for displays. This book highlights developments in materials chemistry and physics relevant to such devices and strikes a balance between basic science and technology. Topics include: nonlinear optical materials; photorefractive polymers; and electronic and light-emitting materials.
This book covers the full spectrum of activity in the GaN and related materials arena. These semiconductors are finding applications in full-color displays, high-density information storage, white lighting for outdoor or backlit displays, solar-blind UV detectors, high-power/high-temperature electronics, and covert undersea communications. Progress is been reported in the growth of thick layers on patterned substrates by various methods, leading to lower overall defect concentrations and improved current-voltage and reliability characteristics. The rapidly increasing market for blue/green LEDs is also noted by the entry of a number of new companies to the field. While these emitter technologies continue to be dominated by MOCVD material, there are exciting reports of UV detectors and HFET structures grown by MBE with device performance at least as good as by MOCVD. Topics include: GaN electronic and photonic devices; laser diodes and spectroscopy; electronic devices and processing; quantum dots and processing; novel growth, doping and processing and rare-earth doping and optical emission.
