The exceptional properties of multicomponent oxides, combined with the inability of simpler materials to meet the increasing demands of the electronics industry, have motivated tremendous interest and activity in utilizing multicomponent oxides for electronic applications. For these applications, it is often desirable to integrate complex oxides in thin-film form with other materials. This book focuses on common materials issues involved in the processing and characterization of multicomponent oxides and how these issues relate to device applications. Papers range from theoretical explanations of the magnetic and electronic properties of transition metal oxides, to integration with silicon technology. Noteworthy is the progress being made in the deposition and characterization of these complex materials, as well as their applicability in ferroelectric memories, MOSFETs, optical devices, infrared imaging arrays, etc. Topics include: epitaxial multicomponent oxide film growth; properties, characterization and modeling; properties of multicomponent oxides; and multicomponent oxide devices.

This book on gallium nitride (GaN) and associated materials focuses on advances in basic science, as well as the rapidly maturing technologies involving blue/green light emitters, detectors and high-power electronics. A highlight is a report on wide-bandgap semiconductor research done in Europe. Also reported is the commercialization of a laser operating at 405nm wavelength with a 4000-hour device lifetime. At 450nm emission wavelength, significant reductions in lifetime were found, and are believed to arise from nonideal properties of the InGaN alloy used in the active layer of the device. Additional topics include: the significant success of transistors for microwave applications; improvements in the epitaxy of GaN, using both selective area growth techniques (lateral epitaxy overgrowth) and introducing low-temperature intralayers in the films; advances in both molecular beam epitaxy and metal-organic vapor phase epitaxy, including several studies of quantum dot formation in strained alloys and improvements in hydride vapor phase epitaxy, particularly for providing very thick films.
Luminescent materials are of interest to members of the spectroscopic, basic science, engineering and display communities. This book presents a wide range of topics from basic research of fluorescence to applications-driven research on phosphors and scintillators. Papers on various luminescent, fluorescent or phosphorescent mechanisms arising in inorganic crystalline and noncrystalline materials, as well as in organic materials, are featured. The use of fluorescence as a sensing technique has emerged as a sensitive and noninvasive way to probe biological activity or measure physical phenomena. To that end, progress in understanding fluorescence, the development of novel applications of fluorescence, and novel material structures are addressed. Phosphors for the emerging flat-panel-display industry are also highlighted. Topics include: inorganic phosphors; thin-film phosphors; synthesis, processing and characterization; mechanisms and defects; organic luminescence and theory and luminescence sensors.
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.
