The MRS Symposium Proceeding series is an internationally recognised reference suitable for researchers and practitioners.

A state-of-the-art description of metastability observed in chalcogenide alloys is presented with the accent on the underlying physics. A comparison is made between sulphur(selenium)-based chalcogenide glasses, where numerous photo-induced phenomena take place entirely within the amorphous phase, and tellurides where a reversible crystal-to-amorphous phase-change transformation is a major effect. Applications of metastability in devices¿optical memories and nonvolatile electronic phase-change random-access memories among others are discussed, including the latest trends. Background material essential for understanding current research in the field is also provided.

"Phase Change Materials: Science and Applications" provides a unique introduction of this rapidly developing field. Clearly written and well-structured, this volume describes the material science of these fascinating materials from a theoretical and experimental perspective. Readers will find an in-depth description of their existing and potential applications in optical and solid state storage devices as well as reconfigurable logic applications. Researchers, graduate students and scientists with an interest in this field will find "Phase Change Materials" to be a valuable reference.

This volume from the 2006 MRS Spring Meeting focuses on fundamental materials science and device research for current transistor technologies. Materials scientists come together with silicon technologists and TCAD researchers and activation technologies for integrated circuits, to discuss current achievements research directions.

This book investigates the fundamental properties and response of materials in extreme environments such as static and dynamic high pressure, high strain and high strain-rates, high radiation and electromagnetic fields, high and low temperatures, corrosive conditions, environments causing embrittlement, and environments containing atomic oxygen. This is an extremely active and vibrant field of research, in particular because it is now possible to create laboratory conditions similar in pressure, temperature and radiation to those found in planetary interiors and in space. In addition, advanced simulation methods, coupled with high-performance computing platforms, now afford predictions - on a first-principles basis - of the properties of materials in extreme environments. Scientists from a broad spectrum of fields are represented, including space science, planetary science, high-pressure research, shock physics, ultrafast science, and energetic materials research.

The MRS Symposium Proceeding series is an internationally recognised reference suitable for researchers and practitioners. This book shares results and physical models related to MOSFETs and to discuss innovative approaches necessary to continue the transistor scaling. Expanded versions of presentations in the areas of technology development are featured
