Solid-State Physics: Introduction to the Theory



James D. Patterson, Bernard C. Bailey , "Solid-State Physics: Introduction to the Theory"
Springer; 1 edition (January 19, 2007) | ISBN: 3540241159 | 717 pages | PDF | 5,9 Mb

Learning solid state physics involves a certain degree of maturity, since it involves tying together diverse concepts from many areas of physics. The objective is to understand, in a basic way, how solid materials behave. To do this one needs both a good physical and mathematical background. One definition of solid state physics is that it is the study of the physical (e.g. the electrical, dielectric, magnetic, elastic, and thermal) properties of solids in terms of basic physical laws. In one sense, solid state physics is more like chemistry than some other branches of physics because it focuses on common properties of large classes of materials. It is typical that solid state physics emphasizes how physics properties link to electronic structure. We have retained the term solid state physics, even though condensed matter physics is more commonly used. Condensed matter physics includes liquids and non-crystalline solids such as glass, which we shall not discuss in detail. Modern solid state physics came of age in the late thirties and forties, and had its most extensive expansion with the development of the transistor, integrated circuits, and microelectronics. Most of microelectronics, however, is limited to the properties of inhomogeneously doped semiconductors. Solid state physics includes many other areas of course; among the largest of these are ferromagnetic materials, and superconductors. Just a little less than half of all working physicists are in condensed matter.

A course in solid state physics typically begins with three broad areas: (1) How and why atoms bind together to form solids, (2) Lattice vibrations and phonons, and (3) Electrons in solids. One would then typically apply the above to (4) Interactions especially of electrons with phonons, (5) Metals, the Fermi surface and alloys, (6) Semiconductors, (7) Magnetism, (8) Superconductivity, (9) Dielectrics and ferroelectrics, (10) Optical properties, (11) Defects, and (12) Certain other modern topics such as layered materials, quantum Hall effect, mesoscopics, nanophysics, and soft condensed matter. In this book, we will consider all of these.

Geology and Geochemistry of Oil and Gas, Volume 52



L. Buryakovsky, N.A. Eremenko, M.V. Gorfunkel, G.V. Chilingarian, "Geology and Geochemistry of Oil and Gas, Volume 52"
Elsevier Science; 1 edition (December 12, 2005) | ISBN: 0444520538 | 390 pages | PDF | 4,2 Mb

This book discusses the progress that is being made through innovations in instrumental measurements of geologic and geochemical systems and their study using modern mathematical modeling. It covers the systems approach to understanding sedimentary rocks and their role in evolution and containment of subsurface fluids.

Fundamental aspects of petroleum geology and geochemistry, generation, migration, accumulation, evaluation and production of hydrocarbons are discussed with worldwide examples. Various physical and chemical properties of subsurface waters, crude oils and natural gases are described which is especially important to production engineering. Among various properties of liquid and gaseous hydrocarbons the most important are wettability affecting production characteristics and ultimate recovery: relative permeability affecting reservoir fluid flow to the production wells; density differences between immiscible fluids which affects gravity drainage; viscosity of subsurface fluids affecting the relative mobility of each fluid; and fluid chemistry, which affects the absorption, ultimate recovery and monetary value of produced hydrocarbons.

Discussion of the formation and accumulation of hydrocarbons includes (1) the changes in the chemical composition of hydrocarbons that originate from the debris of living plants and organisms to form crude oil and natural gas; (2) the origin of hydrocarbons in different areas of a single reservoir; (3) the conditions, which determine the distribution of water, oil and gas in the reservoir; (4) the migration of subsurface fluids until they eventually accumulate in isolated traps; (5) discussion of the traps as a function of sedimentary geology and tectonics. This is based on the systems approach to the specific geologic and geochemical systems using analytical and statistical principles and examples of modern mathematical modeling of static and dynamic systems.

Nanophysics Coherence and Transport, Volume Session LXXXI Lecture Notes of the Les Houches Summer School 2004



H. Bouchiat, Y. Gefen, S. Gueron, G. Montambaux , J. Dalibard , "Nanophysics Coherence and Transport, Volume Session LXXXI Lecture Notes of the Les Houches Summer School 2004"
Elsevier Science (September 29, 2005) | ISBN: 0444520546 | 640 pages | PDF | 6,1 Mb

The developments of nanofabrication in the past years have enabled the design of electronic systems that exhibit spectacular signatures of quantum coherence. Nanofabricated quantum wires and dots containing a small number of electrons are ideal experimental playgrounds for probing electron-electron interactions and their interplay with disorder. Going down to even smaller scales, molecules such as carbon nanotubes, fullerenes or hydrogen molecules can now be inserted in nanocircuits. Measurements of transport through a single chain of atoms have been performed as well. Much progress has also been made in the design and fabrication of superconducting and hybrid nanostructures, be they normal/superconductor or ferromagnetic/superconductor. Quantum coherence is then no longer that of individual electronic states, but rather that of a superconducting wavefunction of a macroscopic number of Cooper pairs condensed in the same quantum mechanical state. Beyond the study of linear response regime, the physics of non-equilibrium transport (including non-linear transport, rectification of a high frequency electric field as well as shot noise) has received much attention, with significant experimental and theoretical insights. All these quantities exhibit very specific signatures of the quantum nature of transport, which cannot be obtained from basic conductance measurements.

Basic concepts and analytical tools needed to understand this new physics are presented in a series of theoretical fundamental courses, in parallel with more phenomenological ones where physics is discussed in a less formal way and illustrated by many experiments.

· Electron-electron interactions in one-dimensional quantum transport
· Coulomb Blockade and Kondo physics in quantum dots
· Out of equilibrium noise and quantum transport
· Andreev reflection and subgap nonlinear transport in hybrid N/S nanosructures.
· Transport through atomic contacts
· Solid state Q-bits
· Written by leading experts in the field, both theorists and experimentalists

Theory of Individual Behavior



Robert Wichers, "Theory of Individual Behavior"
Academic Press; 1st edition (January 15, 1996) | ISBN: 0127484507 | 209 pages | PDF | 10,2 Mb

Review
"Dispels the notion that individuals act as rational agents and strives to capture idiosyncratic humanness through rigorous mathematics. Wichers describes a version of economic behavior that is more comprehensive and satisfying than neoclassical models yet consistent with the usual aggregated concepts that form the basis of applied microeconomics. Contains a short review of mathematical models and discussion of received microeconomic theory, as well as summaries and questions at the ends of chapters.

Ioan D. marinescu "Handbook of Advanced Ceramics Machining"
Publisher: CRC | Pages: 384 | 2006-11-16 | ISBN: 0849338379 | PDF | 7,1 Mb

Ceramics, with their unique properties and diverse applications, hold the potential to revolutionize many industries, including automotive and semiconductors. For many applications, ceramics could replace metals and other materials that are more easily and inexpensively machined. However, current ceramic machining methods remain cost-prohibitive. Fortunately, the current flurry of research will soon yield new and better methods for machining advanced ceramic materials. Reflecting the life-long dedication of an unsurpassed team of experts from industry and academia, the Handbook of Advanced Ceramics Machining explores the latest developments in our understanding of the mechanisms involved in ceramics machining as well as state-of-the-art technologies. Multiple chapters are devoted to various types and aspects of the lapping and grinding processes, such as mechanisms, monitoring techniques, mono- versus polycrystalline abrasives, and tribological properties. Covering methods that offer high-rate material removal and others that provide extremely high-quality surface finish, this book examines conventional, new, and lesser-known methods including ductile grinding, belt centerless grinding, lapping, polishing, double-side grinding, laser-assisted grinding, ultrasonic machining, and the new electrolytic in-process dressing (ELID) grinding method.

Prefacio

En la década transcurrida desde la publicación de la segunda edición, los progresos
logrados en el disefio de reactores han vuelto a hacer necesaria una revisión bastante
completa de todos los capítulos. Esta revisión proporcionó una oportunidad para
mejorar la presentación de los conceptos básicos. Los cambios más importantes de
este tipo se encuentran en los Caps. 3-5. Las ecuaciones de conservación de la masa
del Cap. 3 se han desar;ollado de una manera más general. Esta presentación permi-
te que las expresiones de diseño para formas específicas de reactores, tal como apa-
recen en el resto del libro, se puedan obtener directamente por simplificación de las
ecuaciones generales. El análisis de los reactores con recirculación, que no se incluyó
en la segunda edición, se introduce en el Cap. 4. Los temas de reactores semiconti-
nuos (Cap. 4) se han modificado de tal manera que, junto con los reactores con re-
circulación, proporcionen ilustraciones adicionales de las ecuaciones generales de
conservación de la masa obtenidas en el Cap. 3. Para lograr una presentación m8s
clara, los balances de masa y de energía se estudian como temas completamente se-
parados. De esta manera, la ecuación general de conservación de la energía se de-
sarrolla en el Cap. 5, donde se usa para el diseño de reactores no isotérmicas.

Uno de los principales objetivos de la tercera edición, así como de las anteriores,
consiste en proporcionar ejemplos de diseño de reactores e interpretación de los da-
tos de laboratorio para reacciones químicas reales. Esto suele requerir la inclusión de
cálculos numéricos repetitivos (para la resolución de ecuaciones diferenciales). En la
tercera edición, estos cálculos se basan primordialmente en un método de Runge-
Kutta. Sin embargo, cuando se hace necesario mostrar con más claridad el significa-
do físico de los cálculos, se usa también el método Euler, que es más simple.

Los temas que se presentan en cada capítulo son muy semejantes a los descritos
en forma general por el prefacio de la segunda edición, a excepción de las modifica-
ciones ya señaladas y otras adiciones. El objetivo del libro en su totalidad sigue siendo
el mismo -proporcionar una presentación clara pero razonablemente explicada del
diseño de reactores, con ilustraciones tomadas de sistemas químicos prácticos y rea-
listas-. Este libro debe ser de fácil comprensión para los estudiantes del cuarto y
posiblemente tercer años de los programas universitarios de ingeniería química. La
totalidad de la obra puede estudiarse en dos semestres, aunque en algunos casos.
podría hacerse más intensivo para un solo semestre.
