Download or read book Crystal Growth written by C. H. L. Goodman and published by Springer. This book was released on 2013-04-17 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decade or so the growth of single crystals has assumed enormous importance for both academic research, and technology (particu larly in the field of 'electronics'). The range of fields involved is great: from electro-optics to metal corrosion, from semiconductors to magnetic bubble materials-one can add to the list almost indefinitely. However, while the general principles of crystal growth can be applied aImost right across the board, it turns out that the precise way in which one can grow a particular crystal best varies considerably from material to material. This, of course, is to emphasise the obvious; nonetheless, except in specialised papers in the scientific litera ture , little attempt seems to have been made to deal in any detail with the causes of the difficulties in growing particular kinds of materials and with methods of circumventing them. These specialised papers may be inaccessible, and in any case cannot be, usually, very broad in scope or detailed in treatment simply because of the pressure to keep papers short. And unfortunately few specialised monographs seem to have been produced. These points and others similar emerged repeatedly in discussions with crystal growers from aU parts of the World and indicated that there was a need for a publication which would deal in detail with problems and techniques for specialised areas of crystal growth.
Download or read book Luminescence and the Solid State written by Richard C. Ropp and published by Elsevier. This book was released on 2004-05-06 with total page 731 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the first date of publication of this book in 1991, the subject of phosphors and luminescence has assumed even more importance in the overall scheme of technological development. Many new types of displays have appeared which depend upon phosphors in their operation. Some of these were pure conjecture in 1991 but are a reality in 2004. Descriptions have been included of the newer (as well as the older) types of displays in this edition along with an annotated portrait of the phosphors used in each category. Many of these new light sources promise to displace and make obsolete our current light sources, such as incandescent lamps, fluorescent lamps and the ubiquitous colour Cathode Ray Tube now used in TV and computer monitors. The importance of solid state science are summarized in the introductory chapters of this edition, and many of the chapters have been completely rewritten or revised. Each chapter has a special contribution to make in the overall understanding of the solid state science of phosphors and luminescence. Introduces the reader to the science and art of preparing inorganic luminescent materials Describes how and why luminescent materials exhibit such specific intrinsic properties Describes the science of the solid state and presents the exact formulas and conditions required to make all of the phosphors known at that time
Download or read book Triple Oxygen Isotope Geochemistry written by Ilya N. Bindeman and published by Walter de Gruyter GmbH & Co KG. This book was released on 2021-02-22 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 86 of Reviews in Mineralogy and Geochemistry concentrates on understanding the variations among ratios of the three isotopes of oxygen, with primary emphasis on terrestrial systems. Triple oxygen isotope variations may be related to large, mass-independent fractionation effects such observed in the Earth atmosphere or may be small and related to minute variations due to purely mass-dependent processes. Recent advancements in analytical resolution now allow for the identification of processes and distinct reservoirs that were formerly hidden in the paradigm of a "single terrestrial fractionation line". New, high-resolution measurements are accompanied by advances in theoretical calculations that dovetail with empirical calibrations and applications throughout this volume. 14 chapters span a wide range of subjects: from ab-initio theoretical approaches to observation of triple oxygen isotope variations in the Earth litho-, hydro- and atmosphere.
Download or read book Crystal Pulling from the Melt written by Donald T.J. Hurle and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crystal pulling is an industrial process and provides the bulk of semiconductor crystals for the semiconductor industry. Initially a purely empirical process, the increase in importance and size of the industry has led to basic research into the fundamentals of the process - particularly the modelling of heat and mass transfer. The book has been written by the recognized authority on Czochralski crystal-growth techniques. It is an attempt to strengthen the interface between the practical crystal grower and the applied mathematician involved in analytical and computer modelling. Its focus is on the physics, chemistry and metallurgy of the process. From reviews: "... There is a need for a modern, non-trivial text on Czochralski growth ... and Dr. Hurle is eminently suited to write such a text."; "Dr. Hurle is probably uniquely qualified to write a book on ... (the Czochralski) growth process. ... He has published a great deal of very substantial as well as innovative work in this area."
