Crystals are the unacknowledged pillars of modern technology. The
modern technological developments depend greatly on the
availability of suitable single crystals, whether it is for lasers,
semiconductors, magnetic devices, optical devices, superconductors,
telecommunication, etc. In spite of great technological
advancements in the recent years, we are still in the early stage
with respect to the growth of several important crystals such as
diamond, silicon carbide, PZT, gallium nitride, and so on. Unless
the science of growing these crystals is understood precisely, it
is impossible to grow them as large single crystals to be applied
in modern industry.
This handbook presents electronic structure data and tabulations of Slater-Koster parameters for the whole periodic table. This second edition presents data sets for all elements up to Z = 112, Copernicium, whereas the first edition contained only 53 elements. In this new edition, results are given for the equation of state of the elements together with the parameters of a Birch fit, so that the reader can regenerate the results and derive additional information, such as Pressure-Volume relations and variation of Bulk Modulus with Pressure. For each element, in addition to the equation of state, the energy bands, densities of states and a set of tight-binding parameters is provided. For a majority of elements, the tight-binding parameters are presented for both a two- and three-center approximation. For the hcp structure, new three-center tight-binding results are given. Other new material in this edition include: energy bands and densities of states of all rare-earth metals, a discussion of the McMillan-Gaspari-Gyorffy theories and a tabulation of the electron-ion interaction matrix elements. The evaluation of the Stoner criterion for ferromagnetism is examined and results are tabulated. This edition also contains two new appendices discussing the effects of spin-orbit interaction and a modified version of Harrison's tight-binding theory for metals which puts the theory on a quantitative basis.
New materials addressed for the first time include the chapters
on minerals by Barber et al and the chapter on dislocations in
colloidal crystals by Schall and Spaepen. Moriarty et al extend the
first principles calculations of kink configurations in bcc metals
to high pressures, including the use of flexible boundary
conditions to model dilatational effects. Rabier et al clarify the
issue of glide-shuffle slip systems in diamond cubic and related
III-V compounds. Metadislocations, discussed by Feuerbacher and
Heggen, represent a new type of defect in multicomponent metal
compounds and alloys. Dislocation core structures identified in silicon at high stress Metadislocations, a new type of defect, identified and described Extension of dislocation concepts to complex minerals First observations of dislocations in colloidal crystals
There is no question that the field of solid state electronics,
which essentially began with work at Bell laboratories just after
World War II, has had a profound impact on today's Society. What is
not nearly so widely known is that advances in the art and science
of crystal growth underpin this technology. Single crystals, once
valued only for their beauty, are now found, in one form or another
in most electronic, optoelectronic and numerous optical devices.
These devices, in turn, have permeated almost every home and
village throughout the world. In fact it is hard to imagine what
our electronics industry, much less our entire civilization, would
have been like if crystal growth scientists and engineers were
unable to produce the large, defect free crystals required by
device designers.
Understandable by anyone concerned with crystals or solid state properties dependent on structure Presents a general system using simple notation to reveal similarities and differences among crystal structures More than 300 selected and prepared figures illustrate structures found in thousands of compounds Includes a CD-ROM with CrystalMakerTM data files to allow the reader to view and manipulate the structures
Structure and Dynamics of Macromolecules: Absorption and
Fluorescence Studies is clearly written and contains invaluable
examples, coupled with illustrations that demonstrate a
comprehensible analysis and presentation of the data. This book
offers practical information on the fundamentals of absorption and
fluorescence, showing that it is possible to interpret the same
result in different ways. It is an asset to students, professors
and researchers wishing to discover or use absorption and
fluorescence spectroscopy, and to scientists working on the
structure and dynamics of macromolecules.
Dislocations are lines of irregularity in the structure of a solid
analogous to the bumps in a badly laid carpet. Like these bumps
they can be easily moved, and they provide the most important
mechanism by which the solid can be deformed. They also have a
strong influence on crystal growth and on the electronic properties
of semiconductors.
This book presents selected topics on processing and properties of ferroelectric materials that are currently the focus of attention in scientific and technical research. Ferro-piezoelectric ceramics are key materials in devices for many applications, such as automotive, healthcare and non-destructive testing. As they are polycrystalline, non-centrosymmetric materials, their piezoelectricity is induced by the so-called poling process. This is based on the principle of polarization reversal by the action of an electric field that characterizes the ferroelectric materials. This book was born with the aim of increasing the awareness of the multifunctionality of ferroelectric materials among different communities, such as researchers, electronic engineers, end-users and manufacturers, working on and with ferro-piezoelectric ceramic materials and devices which are based on them. The initiative to write this book comes from a well-established group of researchers at the Laboratories of Ferroelectric Materials, Materials Science Institute of Madrid (ICMM-CSIC). This group has been working in different areas concerning thin films and bulk ceramic materials since the mid-1980s. It is a partner of the Network of Excellence on Multifunctional and Integrated Piezoelectric Devices (MIND) of the EC, in which the European Institute of Piezoelectric Materials and Devices has its origin.
This book focuses on the development of liquid crystal displays (LCDs) and liquid crystal materials (LCs) in Japan. The Committee of Organic Materials Research for Information Sciences of the Japan Society for the Promotion of Science (JSPS) planned the book to document essential LCD innovations and developments since the beginnings of the field-effect LCD technology in 1970. The book illustrates the remarkable effort and progress behind those flat, lightweight, and high-information-content LCDs that have become the indispensable human-machine interface for virtually all electronic devices. In contrast to other publications on this topic, the book illustrates the interdisciplinary character of the LCD technology and its crucial importance for technological progress of the field far beyond displays. It also gives insights into breakthrough innovations not revealed in other publications. Moreover, prospects for the development of LC research toward new fields of applications are provided. In line with its interdisciplinary character, the book targets researchers in basic science as well as engineers and researchers in industry.
X-ray multiple-wave diffraction, sometimes called multiple diffraction or N-beam diffraction, results from the scattering of X-rays from periodic two or higher-dimensional structures, like 2-d and 3-d crystals and even quasi crystals. The interaction of the X-rays with the periodic arrangement of atoms usually provides structural information about the scatterer. Unlike the usual Bragg reflection, the so-called two-wave diffraction, the multiply diffracted intensities are sensitive to the phases of the structure factors in volved. This gives X-ray multiple-wave diffraction the chance to solve the X-ray phase problem. On the other hand, the condition for generating an X ray multiple-wave diffraction is much more strict than in two-wave cases. This makes X-ray multiple-wave diffraction a useful technique for precise measure ments of crystal lattice constants and the wavelength of radiation sources. Recent progress in the application of this particular diffraction technique to surfaces, thin films, and less ordered systems has demonstrated the diver sity and practicability of the technique for structural research in condensed matter physics, materials sciences, crystallography, and X-ray optics. The first book on this subject, Multiple Diffraction of X-Rays in Crystals, was published in 1984, and intended to give a contemporary review on the fundamental and application aspects of this diffraction."
Optically Anomalous Crystals begins with an historical introduction covering the contributions of Brewster, Biot, Mallard, Brauns, Tamman, and many other distinguished crystallographers. From this follows a tutorial in crystal optics. Further chapters discuss the two main mechanisms of optical dissymmetry: the piezo-optic effect, and the kinetic ordering of atoms. The text then tackles complex, inhomogeneous crystals, and the complex optical properties resulting from the superposition of anomalies having various etiologies. The book treats the literature comprehensively, but uses illustrations from the authors' laboratories as the subjects of detailed analyses. This is an invaluable text for crystallographers, mineralogists, and petrologists interested in the growth of minerals and synthetic crystals, and their optical properties. It is also ideally suited to students of optical mineralogy, professional scientists and engineers and historians of science.
Fiber Crystal Growth from the Melt reviews the growth, modelling, characterization and application of single crystal fibers are reviewed. Due to their very large length-to-diameter ratio together with perfect crystallographic structure and chemical homogeneity, such fibers have mechanical and physical properties that approach the theoretical values. Fukuda explains how their ultra-high strength enables their application as reinforcing agents in structural components. And he elucidates how and why fiber crystals are particularly well suited for wave guiding, tunable narrow-band filters and nonlinear optics and for the generation of green, blue and violet wavelenghts, and also as micro lasers and laser modulators. The book is suitable for specialists and students in the fields of materials science, crystal growth, physics, chemistry, crystallography, optics, mechanics and engineering.
In this book, academic researchers and technologists will find important information on the interaction of polymeric and non-polymeric inhibitors with a variety of scale forming crystals such as calcium phosphates, calcium carbonate, calcium oxalates, barium sulfate, calcium pyrophosphates, and calcium phosphonates. Moreover, the book delivers information to plant managers and formulators who would like to broaden and deepen their knowledge about processes involved in precipitation of sparingly soluble salts and learn more about the inhibitory aspects of various commercially available materials. Furthermore, experienced researchers will obtain fruitful and inspiring ideas from the easily accessible information about overlapping research areas, which will promote discoveries of new inhibitors (synthetic and/or natural) for the currently unmet challenges.
This book contains the contributions of 13 well known specialists in the field of solid state chemistry who had been invited as lecturers at a 1992 NATO Advanced Study Institute in Erice, Sicily. The chapters of a more general character concern the use of the space group - subgroup relationships for the recognition of structure families, the crystal chemical formulae (which is a way of denoting simple crystal chemical information in a condensed form), the concepts of atom co-ordination, atom volume and charge transfer and the physicist's view of the bond strength in the solid which is measured by the crystal orbital overlap population. It is demonstrated for the case of ionic compounds that the bond valence method is superior to the old sum-of-radii method for the prediction of interatomic distances. Simple valence electron rules can be applied fto compounds with tetrahedral anion complexes. These rules allow one not only to make predictions on expected structural features of unknown compounds, but also to point out inconsistencies between the reported structure and composition of known compounds. Detailed accounts are presented on the crystal chemistry of the superconducting copper oxides, the sulfosalts, the metal cluster compounds, the silicates and the transition metal borides and related compounds. In the case of intermetalic compounds the intergrowth concept is found to be very useful for an "understanding" of complicated atom arrangements. At the end of each chapter there can be found problems and their solutions. This makes it possible for (advanced) undergraduates in chemistry, physics, metallurgy, materials science and mineralogy to be able to profit from a study of this book.
Crystal growth and nucleation are treated in the specialized literature in different ways depending on the discipline in question (physics, physical chemistry, chemical engineering) and on the theoretical approaches (atomistic vs continuum approach as regards crystal growth, phase vs chemical concept as regards nucleation). This book relates the different approaches to one another, giving preference to atomistic treatments by the methods of statistical thermodynamics and chemical kinetics. This unified approach also facilitates an understanding of some related phenomena of surface physics, such as adsorption, wetting etc. The book allows research novices and graduate students to get an insight into the physics of the phenomena and to interpret some of the experimental results.
Crystal engineering is an interdisciplinary area that cuts across the traditional subdivisions of chemistry. Fuelled by our increasingly precise understanding of the chemistry and properties of supramolecular systems, interest in the potential of the field has increased rapidly. The topics discussed in the 28 contributions in this book provide a state-of-the-art description of the field and offer new research ideas that, if pursued, will serve to strengthen the field at the interface between supramolecular chemistry and materials science.
Since the invention of the first laser 30 years ago, the frequency conversion of laser radiation in nonlinear optical crystals has become an important technique widely used in quantum electronics and laser physics for solving various scientific and engineering problems. The fundamental physics of three-wave light interactions in nonlinear optical crystals is now well understood. This has enabled the production of various harmonic generators, sum-and difference frequency generators, and optical parametric oscillators based on nonlinear optical crystals that are now commercially available. At the same time, scientists continue an active search for novel, highly efficient nonlinear optical materials. Therefore, in our opinion, there is a great need for a handbook of nonlinear optical crystals, intended for specialists and practitioners with an engineering background. This book contains a complete description of the properties and applications of all nonliner optical crystals of practical importance reported in the literature up to the beginning of 1990. In addition, it contains the most important equations for calculating the main parameters (such as phase-matching direction, effective nonlinearity, and conversion efficiency) of nonlinear frequency converters.

The book considers the main growth-related phenomena occurring
during epitaxial growth, such as thermal etching, doping,
segregation of the main elements and impurities, coexistence of
several phases at the crystal surface and segregation-enhanced
diffusion.
Designed for easy use by both beginning and experienced protein
crystallographers, the second edition of Practical Protein
Crystallography is an essential handbook for any scientist
interested in solving a protein structure. The book includes
examples of actual experiments and data, electron density maps, and
computer methods. This second edition has new material covering
CCP4, SHELX, cryocrystallography, MAD and automated fitting.
This book is by far the most comprehensive treatment of point and space groups, and their meaning and applications. Its completeness makes it especially useful as a text, since it gives the instructor the flexibility to best fit the class and goals. The instructor, not the author, decides what is in the course. And it is the prime book for reference, as material is much more likely to be found in it than in any other book; it also provides detailed guides to other sources.Much of what is taught is folklore, things everyone knows are true, but (almost?) no one knows why, or has seen proofs, justifications, rationales or explanations. (Why are there 14 Bravais lattices, and why these? Are the reasons geometrical, conventional or both? What determines the Wigner-Seitz cells? How do they affect the number of Bravais lattices? Why are symmetry groups relevant to molecules whose vibrations make them unsymmetrical? And so on). Here these analyses are given, interrelated, and in-depth. The understanding so obtained gives a strong foundation for application and extension. Assumptions and restrictions are not merely made explicit, but also emphasized.In order to provide so much information, details and examples, and ways of helping readers learn and understand, the book contains many topics found nowhere else, or only in obscure articles from the distant past. The treatment is (often completely) different from those elsewhere. At least in the explanations, and usually in many other ways, the book is completely new and fresh. It is designed to inform, educate and make the reader think. It strongly emphasizes understanding.The book can be used at many levels, by many different classes of readers - from those who merely want brief explanations (perhaps just of terminology), who just want to skim, to those who wish the most thorough understanding. remove remove
