Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates the behavior of two candidate materials (a-SiO2 and MgO) for applications in fusion (e.g., the International Thermonuclear Experimental Reactor ITER) and Generation IV fission reactors. Both parts of the thesis – the development of the ionoluminescence technique and the study of the ion-irradiation effects on both materials – are highly relevant for the fields of the ion-beam analysis techniques and irradiation damage in materials. The research presented determines the microstructural changes at different length scales in these materials under ion irradiation. In particular, it studies the effect of the irradiation temperature using several advanced characterization techniques. It also provides much-needed insights into the use of these materials at elevated temperatures. Further, it discusses the development of the ion-beam-induced luminescence technique in different research facilities around the globe, a powerful in situ spectroscopic characterization method that until now was little known. Thanks to its relevance, rigorosity and quality, this thesis has received twoprestigious awards in Spain and France.

Download or read book Ion Beam Induced Defects and Defect Interactions in Perovskite Structure Titanates written by and published by . This book was released on 1999 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion-beam irradiation of perovskite structures results in the production and accumulation of defects. Below a critical temperature, irradiation also leads to a crystalline-to-amorphous transformation. The critical temperature for amorphization under 800 keV Kr ion irradiation is 425,440 and 550 K for SrTiO3, CaTiO3 and BaTiO3, respectively. The results of ion-channeling studies on SrTiO3 irradiated with 1.0 MeV Au{sup 2+} ions suggest that the crystalline-to-amorphous transformation is dominated by the accumulation and interaction of irradiation-induced defects. In SiTiO3 irradiated with He and 0+ ions at 180 K, isochronal annealing studies indicate that there is significant recovery of defects on both the oxygen and cation sublattices between 200 and 400 K. These results suggest that defect recovery processes may control the kinetics of amorphization. A fit of the direct-impact/defect-stimulated model to the data for SrTiO3 suggests that the kinetics of amorphization are controlled by both a nearly athermal irradiation-assisted recovery process with an activation energy of 0.1 plus or minus 0.05 eV and a thermal defect recovery process with an activation energy of 0.6 plus or minus 0.1 eV. In SrTi03 implanted with 40 keV H+ to 5.0 x 1016 and 1.0 x 1017 ions/cm2, annealing at 470 K increases the backscattering yield from Sr and Ti and is mostly likely due to the coalescence of H2 into bubble nuclei. Annealing at 570 K and higher results in the formation of blisters or large cleaved areas.

Available in PDF, EPUB and Kindle. Book excerpt: The catastrophic effect, as well as a potentially advantageous effect, from energetic beams is the instant high-energy deposition in a local volume, down to the nanoscale, and the rapid cooling processes resulting in changes in the structure and properties of materials that are hard to achieve by other methods. The challenging balance between controlling radiation damage and enhancing material properties has intrigued materials scientists and physicists, as well as engineers in the nuclear and semiconductor industry, and caused them to work closely together for many years. As clearly demonstrated in this volume, many new technologies for creating unique functional devices with energetic particle beams are based on the fundamental study of radiation-induced defect production and evolution. Scientists and engineers working in nuclear engineering, environmental sciences and functional materials share a common language and numerous opportunities for collaboration in this truly interdisciplinary area. Exciting and promising results are presented here, including the most recent progress in fundamental understanding of radiation effects using molecular dynamic (MD) and kinetic Monte Carlo (kMC) simulations, processing of monodisperse nanoparticles by ion implantation, production of a wide variety of nanostructures with the application of focused ion beams (FIB), and creating new types of nanoscale functional devices using high-energy ion tracks. These results demonstrate the important relation between fundamental research on radiation effects and the development of new types of nanoscale functional devices using energetic particles over a wide energy range. Topics include: radiation effects in nuclear materials; ion-beam processing of nanostructures; ion-beam processing of semiconductor devices; ion-beam modification of physical properties; modeling and computer simulation of beam-solid interactions; and ion-beam-assisted deposition and surface modification.
Download or read book Applications of Ion Beams to Metals written by S. T. Picraux and published by Springer. This book was released on 1974-05 with total page 732 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conferences have been held in the past on atomic collision phenomena and on the applications of ion beams to semiconductors. However, within the past year it became apparent that there is a growing new area of active research involving the use of ion beams to modify and study the basic properties of metals. As a result a topical conference was organized to bring together for the first time scientists with a wide range of backgrounds and interests related to this field. This book contains the proceed ings of the International Conference on Applications of Ion Beams to Metals which was held in Albuquerque, New Mexico, October 2-4, 1973. Much of the work presented herein represents ideas and concepts which have had little or no previous exposure in the open literature. The application of ion beams to superconducting prop erties for example is quite new, as is the chapter on ion induced surface reactions, which includes primarily oxidation and corrosion studies of implanted materials. These areas, as well as the chapter on implantation alloy formation, indicate important future areas of the application of ion beams to metals. A reading of the chapters on superconductivity and on oxida tion and corrosion can serve to bring one up to date on nearly all the existing information in these areas of the ion beam mod ification of metals. A broad perspective of the oxidation area is given in the invited paper by G. Dearnaley.

Electrical and Physicochemical Characterization focuses on the physics of the annealing kinetics of the damaged layer. An overview of characterization tehniques and a critical comparison of the information on annealing kinetics is also presented. Provides basic knowledge of ion implantation-induced defects Focuses on physical mechanisms of defect annealing Utilizes electrical and physico-chemical characterization tools for processed semiconductors Provides the basis for understanding the problems caused by the defects generated by implantation and the means for their characterization and elimination
Download or read book Ion Beam Modification of Materials written by J.S. Williams and published by Newnes. This book was released on 2012-12-02 with total page 1157 pages. Available in PDF, EPUB and Kindle. Book excerpt: This conference consisted of 15 oral sessions, including three plenary papers covering areas of general interest, 22 specialist invited papers and 51 contributed presentations as well as three poster sessions. There were several scientific highlights covering a diverse spectrum of materials and ion beam processing methods. These included a wide range of conventional and novel applications such as: optical displays and opto-electronics, motor vehicle and tooling parts, coatings tailored for desired properties, studies of fundamental defect properties, the production of novel (often buried) compounds, and treating biomedical materials. The study of nanocrystals produced by ion implantation in a range of host matrices, particularly for opto-electronics applications, was one especially new and exciting development. Despite several decades of study, major progress was reported at the conference in understanding defect evolution in semiconductors and the role of defects in transient impurity diffusion. The use of implantation to tune or isolate optical devices and in forming optically active centres and waveguides in semiconductors, polymers and oxide ceramics was a major focus of several presentations at the conference. The formation of hard coatings by ion assisted deposition or direct implantation was also an area which showed much recent progress. Ion beam techniques had also developed apace, particularly those based on plasma immersion ion implantation or alternative techniques for large area surface treatment. Finally, the use of ion beams for the direct treatment of cancerous tissue was a particularly novel and interesting application of ion beams.

Download or read book Comprehensive Nuclear Materials written by and published by Elsevier. This book was released on 2020-07-22 with total page 4871 pages. Available in PDF, EPUB and Kindle. Book excerpt: Materials in a nuclear environment are exposed to extreme conditions of radiation, temperature and/or corrosion, and in many cases the combination of these makes the material behavior very different from conventional materials. This is evident for the four major technological challenges the nuclear technology domain is facing currently: (i) long-term operation of existing Generation II nuclear power plants, (ii) the design of the next generation reactors (Generation IV), (iii) the construction of the ITER fusion reactor in Cadarache (France), (iv) and the intermediate and final disposal of nuclear waste. In order to address these challenges, engineers and designers need to know the properties of a wide variety of materials under these conditions and to understand the underlying processes affecting changes in their behavior, in order to assess their performance and to determine the limits of operation. Comprehensive Nuclear Materials, Second Edition, Seven Volume Set provides broad ranging, validated summaries of all the major topics in the field of nuclear material research for fission as well as fusion reactor systems. Attention is given to the fundamental scientific aspects of nuclear materials: fuel and structural materials for fission reactors, waste materials, and materials for fusion reactors. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource of information. Most of the chapters from the first Edition have been revised and updated and a significant number of new topics are covered in completely new material. During the ten years between the two editions, the challenge for applications of nuclear materials has been significantly impacted by world events, public awareness, and technological innovation. Materials play a key role as enablers of new technologies, and we trust that this new edition of Comprehensive Nuclear Materials has captured the key recent developments. Critically reviews the major classes and functions of materials, supporting the selection, assessment, validation and engineering of materials in extreme nuclear environments Comprehensive resource for up-to-date and authoritative information which is not always available elsewhere, even in journals Provides an in-depth treatment of materials modeling and simulation, with a specific focus on nuclear issues Serves as an excellent entry point for students and researchers new to the field

Available in PDF, EPUB and Kindle. Book excerpt: While ion-beam techniques have been used to create thin films in the semiconductor industry for several decades, these methods have been too costly for other surface treatment applications. However, as manufacturing devices become increasingly smaller, the use of a directed-energy ion beam is finding novel industrial applications that require the custom tailoring of new materials and devices, including magnetic storage devices, photonics, opto-electronics, and molecular transport. Engineering Thin Films and Nanostructures with Ion Beams offers a thorough narrative of the recent advances that make this technology relevant to current and future applications. Featuring internationally recognized researchers, the book compiles their expertise in a multidimensional source that: Highlights the mechanisms and visual evidence of the effects of single-ion impacts on metallic surfaces Considers how ion-beam techniques can help achieve higher disk-drive densities Introduces gas-cluster ion-beam technology and reviews its precedents Explains how ion beams are used to aggregate metals and semiconductors into nanoclusters with nonlinear optical properties Addresses current challenges in building equipment needed to produce nanostructures in an industrial setting Examines the combination of ion-beam techniques, particularly with physical vapor deposition Delineates the fabrication of nanopillars, nanoflowers, and interconnected nanochannels in three dimensions by using atomic shadowing techniques Illustrates the production of nanopores of varying dimensions in polymer films, alloys, and superconductors using ion-beam irradiation Shows how fingerprints can be made more reliable as forensic evidence by recoil-mixing them into the substrate using ion beams From the basics of the ion-beam modification of materials to state-of-the-art applications, Engineering Th
Download or read book Beam Effects Surface Topography and Depth Profiling in Surface Analysis written by Alvin W. Czanderna and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many books are available that detail the basic principles of the different methods of surface characterization. On the other hand, the scientific literature provides a resource of how individual pieces of research are conducted by particular labo- tories. Between these two extremes the literature is thin but it is here that the present volume comfortably sits. Both the newcomer and the more mature scientist will find in these chapters a wealth of detail as well as advice and general guidance of the principal phenomena relevant to the study of real samples. In the analysis of samples, practical analysts have fairly simple models of how everything works. Superimposed on this ideal world is an understanding of how the parameters of the measurement method, the instrumentation, and the char- teristics of the sample distort this ideal world into something less precise, less controlled, and less understood. The guidance given in these chapters allows the scientist to understand how to obtain the most precise and understood measu- ments that are currently possible and, where there are inevitable problems, to have clear guidance as the extent of the problem and its likely behavior.

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.
