Available in PDF, EPUB and Kindle. Book excerpt: This monograph reviews the subject of structural disorder in alloys and describes how structural information can be exploited to build sound theoretical descriptions in terms of modified Ising models. Scattering with thermal neutrons and x-rays prove to be complementary approaches to measure the weak diffuse scattering which provides detailed information about the disorder. The authors show how Monte Carlo methods are applied to determine the most realistic effective interactions among the alloying atoms. These results can be used as a benchmark for modern electronic structure calculations. Of more general interest, the limitations of scattering experiments in a determination of an interaction model, and thus also of the structure itself are discussed. Finally, simulations exhibit not only near-surface disordering due to frustration effects but also new possible surface - induced ordering phenomena. Accurate Monte Carlo simulations are used to test existing theories of wetting.

Book excerpt: This thesis applies the theory of lattice dynamics towards two applications: vibrational entropy in alloys and dielectric absorption in oxides. Vibrational entropies between ordered-L12 and disordered phases in the Au3Cu, Cu3Au, Cu3Pd, Pd3Cu, Cu3Pt, Au3Pd, and Pd3Au systems are calculated. This study was done using first-principles energy calculations and the supercell method. Calculated values of ASʻrder-disorder ranged between -0.05 - 0.07 kB. Length-dependent transferable force constants are used to predict vibrational entropies in the Au-Cu, Au-Pd, and Cu-Pd systems. The stiffness of these force constants is obtained from a function that depends on bond length; this function is determined by fitting polynomials to a small set of calculated force constants. Once a function that describes force constant stiffness vs. bond length is determined for a particular pair type, the function can be transferred between different configurations and chemical systems to construct force constants for an arbitrary structure. These transferable force constants are shown to accurately predict vibrational entropies of L12-ordered and disordered phases in Cu3Au, Au3Pd, Pd3Au, Cu3Pd, and Pd3Au. The dielectric absorption at microwave frequencies in binary oxides is calculated within an empirical Buckingham energy model. For MgO, the calculated dielectric losses at room temperature agrees relatively well with experiments, and the temperature dependence is in qualitative agreement. We also model systems to gain insight into the effects of different cation sizes and masses. We explain our results in terms of anharmonic forces, atomic masses, and phonon dispersion curves.

This book was released on 2012-12-06 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last ten years, the physics and technology of low dimensional structures has experienced a tremendous development. Quantum structures with vertical and lateral confinements are now routinely fabricated with feature sizes below 100 run. While quantization of the electron states in mesoscopic systems has been the subject of intense investigation, the effect of confinement on lattice vibrations and its influence on the electron-phonon interaction and energy dissipation in nanostructures received atten tion only recently. This NATO Advanced Research Workshop on Phonons in Sem iconductor Nanostructures was a forum for discussion on the latest developments in the physics of phonons and their impact on the electronic properties of low-dimensional structures. Our goal was to bring together specialists in lattice dynamics and nanos tructure physics to assess the increasing importance of phonon effects on the physical properties of one-(lD) and zero-dimensional (OD) structures. The Workshop addressed various issues related to phonon physics in III-V, II-VI and IV semiconductor nanostructures. The following topics were successively covered: Models for confined phonons in semiconductor nanostructures, latest experimental observations of confined phonons and electron-phonon interaction in two-dimensional systems, elementary excitations in nanostructures, phonons and optical processes in reduced dimensionality systems, phonon limited transport phenomena, hot electron effects in quasi - ID structures, carrier relaxation and phonon bottleneck in quantum dots.

Available in PDF, EPUB and Kindle. Book excerpt: Solid state physicists have long appreciated the usefulness of thermal neutron scattering in the inves tigation of condensed matter. This technique was first made possible by the advent of the nuclear reac tor and has, since then, undergone many refinements. The developments in this field of research have, we felt, necessitated the making of a comprehensive compilation of the published thermal neutron papers. The large number of titles collected in this book, as well as their diversity and their yearly distribution, reflects the continued contribution of the neutron probe to our understanding of physical systems. This bibliography is an updated and improved version of the one first published by us in March of 1973 under a similar title. Many of the omissions and inconsistencies of the first edition, such as occurred, for example, in the initialing of authors' names, have been corrected. The literature search has been carried back to 1932, the year when the existence of the neutron was experimentally confirmed. Several additional journals have also been searched and brought up to date together with those listed in our first publication. The number of entries is now 8543, an increase of 65 per cent relative to the first edition.

This book was released on 2012-05-26 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present book provides to the main ideas and techniques of the rapid progressing field of quantum information and quantum computation using isotope - mixed materials. It starts with an introduction to the isotope physics and then describes of the isotope - based quantum information and quantum computation. The ability to manipulate and control electron and/or nucleus spin in semiconductor devices provides a new route to expand the capabilities of inorganic semiconductor-based electronics and to design innovative devices with potential application in quantum computing. One of the major challenges towards these objectives is to develop semiconductor-based systems and architectures in which the spatial distribution of spins and their properties can be controlled. For instance, to eliminate electron spin decoherence resulting from hyperfine interaction due to nuclear spin background, isotopically controlled devices are needed (i.e., nuclear spin-depleted). In other emerging concepts, the control of the spatial distribution of isotopes with nuclear spins is a prerequisite to implement the quantum bits (or qbits). Therefore, stable semiconductor isotopes are important elements in the development of solid-state quantum information. There are not only different algorithms of quantum computation discussed but also the different models of quantum computers are presented. With numerous illustrations this small book is of great interest for undergraduate students taking courses in mesoscopic physics or nanoelectronics as well as quantum information, and academic and industrial researches working in this field.

Book excerpt: What is the mechanism of the origin of phonon anomalies? Is there any relationship between the phonon anomalies and the structural phase transition? Do the magnetic interactions also contribute significantly to these anomalous characteristics? At least some of the questions, if not all, can be answered by an appropriate microscopic theory of lattice vibrations of these materials. This book examines the central questions mentioned above and their possible solutions with particular reference to transition metals, rare earth metals, their compounds and alloys. The book coherently presents the microscopic theories which have been developed in the last four decades. The available experimental data are presented with an emphasis on their anomalous features
