  • Advances in the Understanding of Crystal Growth Mechanisms

    • 1st Edition
    • T. Nishinaga + 4 more
    • English
    This book contains the results of a research project entitled Crystal Growth Mechanisms on an Atomic Scale, which was carried out for 3 years by some 72 reseachers. Until recently in Japan, only the technological aspects of crystal growth have been emphasized and attention was paid only to its importance in industry. However the scientific aspects also need to be considered so that the technology of crystal growth can be developed even further. This project therefore aimed at understanding crystal growth and the emphasis was on finding growth mechanisms on an atomic scale.

  • Hydrogen in Semiconductors

    • 1st Edition
    • M. Stutzmann + 1 more
    • English
    Hydrogen on semiconductor surfaces has been an area of considerable activity over the last two decades. Structural, thermal, and dynamical properties of hydrogen chemisorbed on crystalline silicon and other semiconductors have been studied in great detail. These properties serve as a reference for related, but more complex systems such as hydrogen at multiple vacancies in crystalline semiconductors or at microvoids in amorphous samples. Interesting from a surface physics point of view is the fact that hydrogen as a monovalent element is an ideal terminator for unsaturated bonds on surfaces and therefore tends to have a large influence on surface reconstruction. A related phenomenon with large technological impact (for example in low cost solar cells) is the passivation of grain boundaries in microcrystalline semiconductors. Finally, hydrogenated semiconductor surfaces always appear as a boundary layer during low-energy hydrogenation of bulk semiconductors, so that a complete description of hydrogen uptake or desorption necessarily has to take these surfaces into account.This collection of invited and contributed papers has been carefully balanced to deal with amorphous and crystalline semiconductors and surfaces and presents basic and experimental work (basic and applied) as well as theory. The resulting volume presents a summary of the state-of-the-art in the field of hydrogen in semiconductors and will hopefully stimulate future work in this area.

  • Random Processes: Measurement, Analysis and Simulation

    • 1st Edition
    • J. Cacko + 2 more
    • English
    This book covers the basic topics associated with the measurement, analysis and simulation of random environmental processes which are encountered in practice when dealing with the dynamics, fatigue and reliability of structures in real environmental conditions. The treatment is self-contained and the authors have brought together and integrated the most important information relevant to this topic in order that the newcomer can see and study it as a whole. This approach should also be of interest to experienced engineers from fatigue laboratories who want to learn more about the possible methods of simulation, especially for use in real time on electrohydraulic computer-controlled loading machines.Problems of constructing a measuring system are dealt with in the first chapter. Here the authors discuss the choice of measuring conditions and locations, as well as the organization of a chain of devices for measuring and recording random environmental processes. Some experience gained from practical measurements is also presented. The recorded processes are further analysed by various methods. The choice is governed by the aims of the measurements and applications of the results. Chapter 2 is thus devoted to methods of random process evaluations for digital computers, both from the fatigue and dynamic point of view. The most important chapter is Chapter 3 as this presents a review of up-to-date methods of random process simulation with given statistical characteristics. These methods naturally follow those of random process analysis, and their results form initial data for the corresponding simulations algorithms, including occurrences of characteristic parameters of counting methods, reproduction of correlation theory characteristics and of autoregressive models. The simulation of non-stationary processes is treated in depth, taking into account their importance for practical applications and also the lack of information of this subject.The book is intended to help resolve many practical problems concerning the methods and quality of environmental process evaluation and simulation which can arise when up-to-date loading systems with computer control are being used in material, component and structural fatigue and dynamic research.

  • Few body dynamics

    • 1st Edition
    • Asoke Mitra
    • English
    Few Body Dynamics presents the proceedings of the VII International Conference on Few Body Problems in Nuclear and Particle Physics, held in Delhi from December 29, 1975 to January 3, 1976. Invited speakers talked about topics ranging from dynamic equations and approximation methods to computation and experimental techniques, few body bound states, breakup reactions and polarization, few electron systems, and photon and electron probes on few body systems. Speakers also covered few body reactions with mesons and resonances, few body aspects of nuclear reactions and scattering, three body forces in nuclei, and quark physics. Comprised of four parts encompassing 145 chapters, this volume summarizes the status and results from experimental facilities such as the Bhabha Atomic Research Centre in India, TRIUMF in Canada, and the Clinton P. Anderson Meson Physics Facility in the United States. It also discusses completeness relations in scattering theory for non-Hermitian potentials, ambiguities in phase-shift analysis, and parametrization of the half-shell function when the eigenchannel has a bound state. The next chapters focus on possible phenomenological forms for the two-body local potential, nuclear three-body forces arising from triple-boson couplings, and concepts such as N-particle transit operators, three-body separable expansion amplitude, the three-body problem with energy-dependent potentials, and the four-body problem. The book also introduces the reader to triton with realistic potentials, backward proton-deuteron scattering, and deep inelastic lepton-nucleon interactions at high energy. This book will benefit physicists, students, and researchers who want to learn about the dynamics of few body systems.

  • Spin Waves and Magnetic Excitations

    • 1st Edition
    • English
    Modern Problems in Condensed Matter Sciences, Volume 22.2: Spin Waves and Magnetic Excitations focuses on the processes, methodologies, reactions, principles, and approaches involved in spin waves and magnetic excitations, including magnetic systems, fluctuations, resonance, and spin dynamics. The selection first elaborates on spin-wave resonance in metals, excitations in low-dimensional magnetic systems, and the theory of magnetic excitations in disordered systems. Topics include spin waves in ferromagnets with weak fluctuations of the exchange interaction; dynamics of propagating excitations; models of two-dimensional magnetic systems; spin-wave resonance in bulk metals; and standing spin-wave resonance in thin films. The manuscript then ponders on spin dynamics of amorphous magnets and magnetic excitations in spin glasses, including dynamics in reentrant spin glasses, dynamics of classical spin glasses, spin dynamical theory, spin dynamics of locally isotropic materials, and effects of dilution. The book takes a look at nuclear spin and magnetoelastic excitations and magnetic impuritons in antiferromagnetic dielectric crystals. Discussions focus on coherent and incoherent impurity excitations, equations of motion and the energy of a magnetoelastic medium, magnetoelastic excitations near magnetic orientational phase transitions, and the effect of frequency pulling on the behavior of nuclear spin echo signals. The selection is a vital source of data for researchers interested in spin waves and magnetic excitations.

  • Principles of Laser Dynamics

    • 1st Edition
    • Y.I. Khanin
    • English
    This monograph summarizes major achievements in laser dynamics over the past three decades. The book begins with two introductory Chapters. Chapter 1 offers general considerations on quantum oscillators, formulates the requirements for the laser key elements and shows how these requirements are met in different laser systems. The second Chapter proposes the mathematical models used in semiclassical laser theory, discusses the approximations and simplifications in particular cases, and specifies the range of applicability of these models. In Chapters 3-5 attention is given primarily to the steady states and their stability, the laser behavior in the instability domain, the characteristics of regular and chaotic pulsations and the nature of their mechanisms.Chapter 6 deals with the processes in a laser, accompanying the time variance of laser parameters. Considerable attention is given to a laser response to weak, low-frequency modulation of the parameters. The problems addressed therein are resonant modulation enhancement, transition to the nonlinear regime, chaotic response to periodic impact, spike-like generation due to variation of the cavity geometry and a laser rod temperature drift.Laser behavior is subject to qualitative changes if its optical elements exhibit nonlinear properties. The action of a saturable absorber, which leads to a loss of laser stability and provides passive Q-modulation, is investigated. To a much lesser degree the researchers' attention has been attracted by other nonlinear effects such as self-focusing, e.g., which may have a strong influence on laser dynamics. All of these issues are covered in Chapter 7.The book is intended for researchers, engineers, graduate and post-graduate students majoring in quantum electronics.
