Available in PDF, EPUB and Kindle. Book excerpt: ``Physics of Radiation Effects in Crystals'' is presented in two parts. The first part covers the general background and theory of radiation effects in crystals, including the theory describing the generation of crystal lattice defects by radiation, the kinetic approach to the study of the disposition of these defects and the effects of the diffusion of these defects on alloy compositions and phases. Specific problems of current interest are treated in the second part and include anisotropic dimensional changes in x-uranium, zirconium and graphite, acceleration of thermal creep in reactor materials, and radiation damage of semiconductors and superconductors.

Download or read book Physical Processes in Inorganic Scintillators written by Piotr A. Rodnyi and published by CRC Press. This book was released on 2020-12-17 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last ten to fifteen years, researchers have made considerable progress in the study of inorganic scintillators. New scintillation materials have been investigated, novel scintillation mechanisms have been discovered, and additional scintillator applications have appeared. Demand continues for new and improved scintillation materials for a variety of applications including nuclear and high energy physics, astrophysics, medical imaging, geophysical exploration, radiation detection, and many other fields. However, until now there have been no books available that address in detail the complex scintillation processes associated with these new developments. Now, a world leader in the theory and applications of scintillation processes integrates the latest scientific advances of scintillation into a new work, Physical Processes in Inorganic Scintillators. Written by distinguished researcher Piotr Rodnyi, this volume explores this challenging subject, explains the complexities of scintillation from a modern point of view, and illuminates the way to the development of better scintillation materials. This unique work first defines the fundamental physical processes underlying scintillation and governing the primary scintillation characteristics of light output, decay time, emission spectrum, and radiation hardness. The book then discusses the complicated mechanisms of energy conversion and transformation in inorganic scintillators. The section on the role of defects in energy transfer and scintillation efficiency will be of special interest. Throughout, the author does not offer complicated derivations of equations but, instead, presents useful equations with practical results.

This book was released on 1995-01-31 with total page 702 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of advanced materials with preselected properties is one of the main goals of materials research. Of especial interest are electronics, high-temperature and superhard materials for various applications, as well as alloys with improved wear, corrosion and mechanical resistance properties. The technical challenge connected with the production of these materials is not only associated with the development of new specialised preparation techniques but also with quality control. The energetic charged particle, electron and photon beams offer the possibility of modifying the properties of the near-surface regions of materials without seriously affecting their bulk, and provide unique analytical tools for testing their quality. Application of Particle and Laser Beams in Materials Technology provides an overview of this rapidly expanding field. Fundamental aspects concerning the interactions and collisions on atomic, nuclear and solid state scale are presented in a didactic way, along with the application of a variety of techniques for the solution of problems ranging from the development of electronics materials to corrosion research and from archaeometry to environmental protection. The book is divided into six thematic units: Fundamentals, Surface Analysis Techniques, Laser Beams in Materials Technology, Accelerator-Based Techniques in Materials Technology, Materials Modification and Synchrotron Radiation.

This book was released on 2012-03-31 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiation Processes In Crystal Solid Solutions is a monograph explaining processes occurring in two classes of crystal solids (metal alloys and doped alkali halides) under irradiation by various types of radiation (alpha, beta, gamma, X-radiations, ions). While metal alloys may differ in high radiation stability, solid solutions based on alkali halides are very radiation-sensitive materials. Radiation defect production mechanisms, intrinsic and extrinsic radiation defects, a role of complexes an impurity-radiation defect which explain distinction in radiating stability of the specified classes of solid solutions are discussed in this e-book. To describe radiation induced phase transformations, two approaches are highlighted: kinetic and thermodynamic. This e-book also includes research on the effect of small radiation doses in a structurally solid phase state of a solution along with a semi-quantitative estimation of radiation effects with respect to temperature changes. This e-book should be a useful reference for advanced readers interested in the physics of radiation and solid state physics.

Download or read book Defects and Surface Induced Effects in Advanced Perovskites written by Gunnar Borstel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complex oxide materials, especially the ABO3-type perovskite materials, have been attracting growing scientific interest due to their unique electro-optical properties, leading to photorefractive effects that form the basis for such devices as holographic storage, optical data processing and phase conjugation. The optical and mechanical properties of non-metals are strongly affected by the defects and impurities that are unavoidable in any real material. Nanoscopically sized surface effects play an important role, especially in multi-layered ABO3 structures, which are good candidates for high capacity memory cells. The 51 papers presented here report the latest developments and new results and will greatly stimulate progress in high-tech technologies using perovskite materials.
