Available in PDF, EPUB and Kindle. Book excerpt: Statistical Thermodynamics of Semiconductor Alloys is the consideration of thermodynamic properties and characteristics of crystalline semiconductor alloys by the methods of statistical thermodynamics. The topics presented in this book make it possible to solve such problems as calculation of a miscibility gap, a spinodal decomposition range, a short-range order, deformations of crystal structure, and description of the order-disorder transitions. Semiconductor alloys, including doped elemental semiconductors are the basic materials of solid-state electronics. Their structural stability and other characteristics are key to determining the reliability and lifetime of devices, making the investigation of stability conditions an important part of semiconductor physics, materials science, and engineering. This book is a guide to predicting and studying the thermodynamic properties and characteristics of the basic materials of solid-state electronics. Includes a complete and detailed consideration of the cluster variation method (CVM) Provides descriptions of spinodal decomposition ranges of crystalline alloys Presents a representation of thermodynamics characteristics and properties as a miscibility gap by using the different approximations of CVM Covers a unique, detailed consideration of the valence force field model with the complete collection of formulas

Available in PDF, EPUB and Kindle. Book excerpt: This book is intended for scientists, researchers, and graduate students interested in solutions in general, and solutions of metals in particular. Readers are assumed to have a good background in thermodynamics, presented in such books as those cited at the end of Chapter 1, "Thermo dynamic Background." The contents of the book are limited to the solutions of metals + metals, and metals + metalloids, but the results are also appli cable to numerous other types of solutions encountered by metallurgists, materials scientists, geologists, ceramists, and chemists. Attempts have been made to cover each topic in depth with numerical examples whenever necessary. Chapter 2 presents phase equilibria and phase diagrams as related to the thermodynamics of solutions. The emphasis is on the binary diagrams since the ternary diagrams can be understood in terms of the binary diagrams coupled with the phase rule, and the Gibbs energies of mixing. The cal culation of thermodynamic properties from the phase diagrams is not emphasized because such a procedure generally yields mediocre results. Nevertheless, the reader can readily obtain thermodynamic data from phase diagrams by reversing the detailed process of calculation of phase diagrams from thermodynamic data. Empirical rules on phase stability are given in this chapter for a brief and clear understanding of the physical and atomistic factors underlying the alloy phase formation.

Book excerpt: Festkorper Probleme XIII: Advances in Solid State Physics is a collection of papers from plenary lectures of the solid states division of the German Physical Society in Munster, on March 19-24, 1973. This collection deals with semiconductor physics, surface phenomena, and surface physics. One paper reviews the findings on experiments on the magnetic, optical, electrical, and structural properties of layer type crystals, particularly metal dichalcogenides. This book then discusses the van der Waals attraction using semi-classical methods to explain the correlation in different atoms. This discussion explains the application of the Schrodinger formalism and the Maxwell equations. One paper also reviews the energy distribution of electrons emitted from solids after ultraviolet radiation or monochromatic X-ray exposure. Another paper reviews the use of clean silicon surfaces associated with electron emitters showing ""negative electron affinity."" A paper then reviews the mechanism of charge-transfer devices, with emphasis on the physics of the transfer processes that happen in surface charge-coupled devices or bulk-charge-couple devices. This compendium will prove useful for materials physicists, scientists, and academicians in the field of advanced physics.

This book was released on 2012-12-06 with total page 725 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of phase transformations in substitutional alloys, including order disorder phenomena and structural transformations, plays a crucial role in understanding the physical and mechanical properties of materials, and in designing alloys with desired technologically important characteristics. Indeed, most of the physical properties, including equilibrium properties, transport, magnetic, vibrational as well as mechanical properties of alloys are often controlled by and are highly sensitive to the existence of ordered compounds and to the occurrence of structural transformations. Correspondingly, the alloy designer facing the task of processing new high-performance materials with properties that meet specific industrial applications must answer the following question: What is the crystalline structure and the atomic configuration that an alloy may exhibit at given temperature and concentration? Usually the answer is sought in the phase-diagram of a relevant system that is often determined experimentally and does not provide insight to the underlying mechanisms driving phase stability. Because of the rather tedious and highly risky nature of developing new materials through conventional metallurgical techniques, a great deal of effort has been expended in devising methods for understanding the mechanisms contrOlling phase transformations at the microscopic level. These efforts have been bolstered through the development of fully ab initio, accurate theoretical models, coupled with the advent of new experimental methods and of powerful supercomputer capabilities.

Download or read book Theory of the Thermal Conductivity of Metals Alloys and Semiconductors written by John R. Madigan and published by . This book was released on 1963 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lattice thermal conductivity of simple alloys can be calculated by assuming that the only effects of alloying on the thermal conductivity can be represented by point defect scattering mechanisms. The scattering of phonons by point defects has an inverse relaxation time proportional to the fourth power of the frequency. The proportionality constant depends on the particular scattering mechanism considered. In simple substitutional alloys where one chemically similar element is substituted for another there are three scattering processes to be considered besides phonon-phonon scattering. Phonons are scattered by the fluctuation in mass, the change in force constants, and the lattice distortion caused by the impurity atom. The relaxation time for all these processes acting simultaneously has been derived. The relaxation time for phonon-phonon scattering due to cubic anharmonic terms in the expansion of the potential energy of the crystal in the displacements of the atoms comprising the crystal from equilibrium is proportional to the inverse frequency squared. When the relaxation time for point defect scattering is combined with that for phonon-phonon scattering to obtain an effective relaxation time one may calculate the lattice thermal conductivity as a function of alloy composition. We have done this for the case of Ge-Si alloys and find reasonable agreement with the experiment. The possibility of modifying the theory with the aid of ideas from nonequilibrium statistical mechanics is considered.

Download or read book Ternary Alloys Based on II VI Semiconductor Compounds written by Vasyl Tomashyk and published by CRC Press. This book was released on 2013-07-29 with total page 563 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doped by isovalent or heterovalent foreign impurities (F), II–VI semiconductor compounds enable control of optical and electronic properties, making them ideal in detectors, solar cells, and other precise device applications. For the reproducible manufacturing of the doped materials with predicted and desired properties, manufacturing technologists need knowledge of appropriate ternary system phase diagrams. A guide for technologists and researchers at industrial and national laboratories, Ternary Alloys Based on II-VI Semiconductor Compounds collects all available data on ternary II–VI–F semiconductor materials. It presents ternary phase diagrams for the systems and includes data about phase equilibriums on the cross sections. The book is also suitable for phase diagram researchers, inorganic chemists, and solid state physicists as well as students in materials science, engineering, physical chemistry, and physics. The authors classify all materials according to the periodic groups of their constituent atoms (i.e., possible combinations of Zn, Cd, and Hg with chalcogens S, Se, and Te) and additional components in the order of their group number. Each ternary system database description contains the diagram type, possible phase transformation and physical–chemical interaction of the components, equilibrium investigation methods, thermodynamic characteristics, and the sample preparation method. In some cases, the book illustrates the solid and liquid-phase equilibriums with vapor because of their importance to crystal growth using the vapor–liquid–solid technique. It also presents data on the homogeneity range as well as baric and temperature dependences of solubility impurities in the semiconductor lattice and the liquid phase.
