New Kinds Of Phase Transitions Transformation In Disordered Substances

Proceedings of the NATO Advanced Research Workshop, held in Volga River, Russia, 24-28 May 2001

High-pressure science has undergone a revolution in the last 15 years. The development of intense new x-ray and neutron sources, improved detectors, new instrumentation, greatly increased computation power, and advanced computational algorithms have enabled researchers to determine the behavior of matter at static pressures in excess of 400 GPa. Shock-wave techniques have allowed access to the experimental pressure-temperature range beyond 1 TPa and 10,000 K. High-Pressure Physics introduces the current state of the art in this field. Based on lectures presented by leading researchers at the 63rd Scottish Universities Summer School in Physics, the book summarizes the latest experimental and theoretical techniques. Highlighting applications in a range of physics disciplines—from novel materials synthesis to planetary interiors—this book cuts across many areas and supplies a solid grounding in high-pressure physics. Chapters cover a wide array of topics and techniques, including: High-pressure devices The design of pressure cells Electrical transport experiments The fabrication process for customizing diamond anvils Equations of state (EOS) for solids in a range of pressures and temperatures Crystallography, optical spectroscopy, and inelastic x-ray scattering (IXS) techniques Magnetism in solids The internal structure of Earth and other planets Measurement and control of temperature in high-pressure experiments Solid state chemistry and materials research at high pressure Liquids and glasses The study of hydrogen at high density A resource for graduate students and young researchers, this accessible reference provides an overview of key research areas and applications in high-pressure physics.

This book gathers selected papers that were submitted to the 2021 International Conference on Comprehensible Science (ICCS 2021) that aims to make available the discussion and the publication of papers on all aspects of single and multi-disciplinary research on conference topics. ICCS 2021 held on June 18–19, 2021. An important characteristic feature of conference is the short publication time and worldwide distribution. Written by respected researchers, the book covers a range of innovative topics related to: artificial intelligence research; big data and data mining; blockchain and cryptocurrency; business, finance and accounting and statistics; cyber security systems; ecology systems; educational technologies; engineering and technology; innovative economics; media technologies; medicine, public health and rehabilitation; nutrition and diet researches; physical and material sciences; and smart cities and contracts. This book may be used for private and professional non-commercial research and classroom use (e.g., sharing the contribution by mail or in hard copy form with research colleagues for their professional non-commercial research and classroom use); for use in presentations or handouts for any level students, researchers, etc.; and for the further development of authors’ scientific career (e.g., by citing and attaching contributions to job or grant application).

This book presents materials fundamentals of novel gate dielectrics that are being introduced into semiconductor manufacturing to ensure the continuous scalling of the CMOS devices. This is a very fast evolving field of research so we choose to focus on the basic understanding of the structure, thermodunamics, and electronic properties of these materials that determine their performance in device applications. Most of these materials are transition metal oxides. Ironically, the d-orbitals responsible for the high dielectric constant cause sever integration difficulties thus intrinsically limiting high-k dielectrics. Though new in the electronics industry many of these materials are wel known in the field of ceramics, and we describe this unique connection. The complexity of the structure-property relations in TM oxides makes the use of the state of the art first-principles calculations necessary. Several chapters give a detailed description of the modern theory of polarization, and heterojunction band discontinuity within the framework of the density functional theory. Experimental methods include oxide melt solution calorimetry and differential scanning calorimetry, Raman scattering and other optical characterization techniques, transmission electron microscopy, and x-ray photoelectron spectroscopy. Many of the problems encounterd in the world of CMOS are also relvant for other semiconductors such as GaAs. A comprehensive review of recent developments in this field is thus also given. The book should be of interest to those actively engaged in the gate dielectric research, and to graduate students in Materials Science, Materials Physics, Materials Chemistry, and Electrical Engineering.

Volume 63 of Reviews in Mineralogy and Geochemistry provides an introduction for those not yet familiar with neutrons by describing basic features of neutrons and their interaction with matter as well illustrating important applications. The volume is divided into 17 Chapters. The first two chapters introduce properties of neutrons and neutron facilities, setting the stage for applications. Some applications rely on single crystals (Chapter 3) but mostly powders (Chapters 4-5) and bulk polycrystals (Chapters 15-16) are analyzed, at ambient conditions as well as low and high temperature and high pressure (Chapters 7-9). Characterization of magnetic structures remains a core application of neutron scattering (Chapter 6). The analysis of neutron data is not trivial and crystallographic methods have been modified to take account of the complexities, such as the Rietveld technique (Chapter 4) and the pair distribution function (Chapter 11). Information is not only obtained about solids but about liquids, melts and aqueous solutions as well (Chapters 11-13). In fact this field, approached with inelastic scattering (Chapter 10) and small angle scattering (Chapter 13) is opening unprecedented opportunities for earth sciences. Small angle scattering also contributes information about microstructures (Chapter 14). Neutron diffraction has become a favorite method to quantify residual stresses in deformed materials (Chapter 16) as well as preferred orientation patterns (Chapter 15). The volume concludes with a short introduction into neutron tomography and radiography that may well emerge as a principal application of neutron scattering in the future (Chapter 17).

The Physics of Phase Transitions occupies an important place at the crossroads of several fields central to materials sciences. This second edition incorporates new developments in the states of matter physics, in particular in the domain of nanomaterials and atomic Bose-Einstein condensates where progress is accelerating. New information and application examples are included. This work deals with all classes of phase transitions in fluids and solids, containing chapters on evaporation, melting, solidification, magnetic transitions, critical phenomena, superconductivity, and more. End-of-chapter problems and complete answers are included.
