Download and read online ebook Thermodynamics of Point Defects and Their Relation with Bulk Properties write by P.A. Varotsos. This book was released on 2013-10-22. Thermodynamics of Point Defects and Their Relation with Bulk Properties available in PDF, EPUB and Kindle. Defects in Solids, Volume 14: Thermodynamics of Point Defects and Their Relation with Bulk Properties focuses on the methodologies, approaches, and reactions involved in the study of point defects in solids. The book first offers information on thermodynamic functions and formation of vacancies. Topics include parameters from the comparison with isochoric perfect crystal; relation between isobaric and isochoric parameters; temperature dependence of thermodynamic functions of solids; and statistical approach to vacancy parameters. The text then ponders on the formation of other point defects, migration, and thermodynamics of specific heat. The publication explains the analysis of experiments yielding defect parameters, including X-ray parameters, analysis of specific heat measurements, and ionic conductivity and reorientation of dipoles. The text also takes a look at mixed alkali and silver halides, explanation of empirical laws, as well as explanation of the empirical laws connecting activation entropy and enthalpy to the activation volume and variation of the bulk modulus with composition. The selection is a dependable reference for scientists and geophysicists interested in the thermodynamics of point defects.

Download and read online ebook Charged Semiconductor Defects write by Edmund G. Seebauer. This book was released on 2008-11-14. Charged Semiconductor Defects available in PDF, EPUB and Kindle. Defects in semiconductors have been studied for many years, in many cases with a view toward controlling their behaviour through various forms of “defect engineering”. For example, in the bulk, charging significantly affects the total concentration of defects that are available to mediate phenomena such as solid-state diffusion. Surface defects play an important role in mediating surface mass transport during high temperature processing steps such as epitaxial film deposition, diffusional smoothing in reflow, and nanostructure formation in memory device fabrication. “Charged Defects in Semiconductors” details the current state of knowledge regarding the properties of the ionized defects that can affect the behaviour of advanced transistors, photo-active devices, catalysts, and sensors. Features: group IV, III-V, and oxide semiconductors; intrinsic and extrinsic defects; and, point defects, as well as defect pairs, complexes and clusters.

Lecture Notes On Equilibrium Point Defects And Thermophysical Properties Of Metals available in PDF, EPUB and Kindle. Despite the significant progress in the study of point defects in metals, some important problems still do not have unambiguous solutions. One of the most practically important questions relates to equilibrium defect concentrations. There exist two opposite viewpoints: (1) defect contributions to physical properties of metals at high temperatures are small and cannot be separated from the effects of anharmonicity; the equilibrium defect concentrations at the melting points are in the range of 10-4 to 10-3; (2) in many cases, defect contributions to the specific heat of metals are much larger than nonlinear effects of anharmonicity and can be separated without crucial errors; the equilibrium concentrations at the melting points are of the order of 10-3 in low-melting-point metals and 10-2 in high-melting-point metals.This book discusses the experimental results and theoretical considerations favoring each claim. At present, the majority of the scientific community hold the first viewpoint. Regrettably, the data supporting the second viewpoint have never been displayed and discussed together, and the criticism of this viewpoint has never included a detailed analysis. Important arguments supporting this viewpoint have appeared in the last decade. It may turn out that just calorimetric determinations provide the most reliable values of equilibrium defect concentrations in metals. In this book, the main attention is paid to equilibrium point defects in metals and their relation to thermophysical properties of metals. Along with a discussion on experimental data and theoretical estimates now available, some approaches are proposed that seem to be most suitable for settling the question.

Download and read online ebook Asymmetric Continuum write by Roman Teisseyre. This book was released on 2013-09-24. Asymmetric Continuum available in PDF, EPUB and Kindle. This book deals with a class of basic deformations in Asymmetric Continuum Theory. It describes molecular deformations and transport velocities in fluids, strain deformations in solids as well as the molecular transport, important in fracture processes. In solids, a separate problem relates to the displacements; their recording, e.g., by means of the seismometers, proves only the existence of the displacement derivatives and not a real displacement. However, the molecular displacements and new fracture criterion including the defect distributions and induced strains are defined in the book too. In fluids, the transport velocities and molecular strains describe the motion processes. The vortex motions are defined by means of the rotational transport; this approach leads to more complicated problems, like the turbulence phenomena. The interaction processes, including the electric and magnetic fields, and some thermodynamical problems and quantum theory analogies help to understand the extreme processes

Earthquake Prediction by Seismic Electric Signals available in PDF, EPUB and Kindle. As evidenced dramatically and tragically in 2011 alone,earthquakes cause devastation and their consequences in terms of human suffering and economic disaster can last for years or even decades. The VAN method of earthquake prediction, based on the detection and measurement of low frequency electric signals called Seismic Electric Signals (SES), has been researched and evaluated over 30 years, and now constitutes the only earthquake prediction effort that has led to concrete successful results. This book recounts the history of the VAN method, detailing how it has developed and been tested under international scrutiny. Earthquake Prediction by Seismic Electric Signals • describes, step by step, the development of the VAN method since 1981; • explains both the theoretical model underpinning the research and the physical properties of SES; • analyzes the SES recordings and the prediction for each major earthquake in Greece over the last 25 years; • introduces a new time domain, natural time, which plays a key role in predicting impending catastrophic events.
