Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest advances and future trends in electron and phonon spectrometrics, focusing on combined techniques using electron emissions, electron diffraction, and phonon absorption and reflection spectrometrics from a substance under various perturbations to obtain new information on bond-electron-phonon dynamics. Discussing the principles of the bond order-length-strength (BOLS) correlation, nonbonding electron polarization (NEP), local bond average (LBA), and multi-field lattice oscillation dynamics for systems under perturbation, the book covers topics like differential photoelectron/phonon spectrometrics (DPS), which distils transition of the length, energy, stiffness and the fraction of bonds upon chemical or physical conditioning; and the derived performance of electrons in various bands in terms of quantum entrapment and polarization. This book appeals to researchers, scientists and engineers in the fields of chemistry, physics, surface and interface science, and materials science and engineering who are interested in electron and phonon spectrometrics.

Available in PDF, EPUB and Kindle. Book excerpt: The physics of nonequilibrium electrons and phonons in semiconductors is an important branch of fundamental physics that has many practical applications, especially in the development of ultrafast and ultrasmall semiconductor devices. This volume is devoted to different trends in the field which are presently at the forefront of research. Special attention is paid to the ultrafast relaxation processes in bulk semiconductors and two-dimensional semiconductor structures, and to their study by different spectroscopic methods, both pulsed and steady-state. The evolution of energy and space distribution of nonequilibrium electrons and the relaxation kinetics of hot carriers and phonons are considered under various conditions such as temperature, doping and pumping intensity by leading experts in the field.

Book excerpt: The generation and propagation of pulses of nonequilibrium acoustic phonons and their interaction with semiconductor nanostructures are investigated. Such studies can give unique information about the properties of low-dimensional electron systems, but in order to interpret the experiments and to understand the underlying physics, a comparison with theoretical models is absolutely necessary. A central point of this work is therefore a universal theoretical approach allowing the simulation and the analysis of phonon spectroscopy measurements on low-dimensional semiconductor structures. The model takes into account the characteristic properties of the considered systems. These properties are the elastic anisotropy of the substrate material leading to focusing effects and highly anisotropic phonon propagation, the anisotropic nature of the different electron-phonon coupling mechanisms, which depend manifestly on phonon wavevector direction and polarization vector, and the sensitivity to the confinement parameters of the low-dimensional electron systems. We show that screening of the electron-phonon interaction can have a much stronger influence on the results of angle-resolved phonon spectroscopy than expected from transport measurements. Since we compare theoretical simulations with real experiments, the geometrical arrangement and the spatial extension of phonon source and detector are also included in the approach enabling a quantitative analysis of the data this way. To illustrate the influence of acoustic anisotropy and carrier confinement on the results of phonon spectroscopy in detail we analyse two different applications. In the first case the low-dimensional electron system acts as the phonon detector and the phonon induced drag current is measured. Our theoretical model enables us to calculate the electric current induced in low-dimensional electron systems by pulses of (ballistic) nonequilibrium phonons. The theoretical drag patterns reproduce the main featu.

Download or read book Introduction To Phonons And Electrons written by Liang-fu Lou and published by World Scientific. This book was released on 2003-08-12 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on phonons and electrons, which the student needs to learn first in solid state physics. The required quantum theory and statistical physics are derived from scratch. Systematic in structure and tutorial in style, the treatment is filled with detailed mathematical steps and physical interpretations. This approach ensures a self-sufficient content for easier teaching and learning. The objective is to introduce the concepts of phonons and electrons in a more rigorous and yet clearer way, so that the student does not need to relearn them in more advanced courses. Examples are the transition from lattice vibrations to phonons and from free electrons to energy bands.The book can be used as the beginning module of a one-year introductory course on solid state physics, and the instructor will have a chance to choose additional topics. Alternatively, it can be taught as a stand-alone text for building the most-needed foundation in just one semester.

Book excerpt: This book features the latest advances and future trends in water science and technology. It also discusses the scientific popularization and quantitative resolution of a variety of mysterious properties of water and ice from the perspective of hydrogen-bond cooperativity in response to stimuli such as chemical contamination, electrification, magnetification, mechanical compression, molecular undercoordination, and thermal excitation. Anomalies include the floating of ice, the Hofmeister effect in solutions, regelation of ice, slipperiness of ice, water’s tough skin, the Mpemba paradox, and the floating bridge. It also addresses the superfluidity of microchannels, hydrogen bond potentials, nanodroplet and bubble thermodynamics, quasisolidity and supersolidity, controlling superhydrophobicity–superhydrophilicity transition, and high-pressure ice formation. The target audience for this book includes students, senior scholars, engineers and practitioners in the area of physical chemistry, biology, as well as aqueous and colloid solutions.

This book was released on 2012-12-06 with total page 1098 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the first edition of this book was published early in 1970, three major developments have occurred in the field of x-ray spectrochemical analysis. First, wavelength-dispersive spectrometry, in 1970 already securely established among instrumental analytical methods, has matured. Highly sophisticated, miniaturized, modular, solid-state circuitry has replaced elec tron-tube circuitry in the readout system. Computers are now widely used to program and control fully automated spectrometers and to store, process, and compute analytical concentrations directly and immediately from ac cumulated count data. Matrix effects have largely yielded to mathematical treatment. The problems associated with the ultralong-wavelength region have been largely surmounted. Indirect (association) methods have extended the applicability of x-ray spectrometry to the entire periodic table and even to certain classes of compounds. Modern commercial, computerized, auto matic, simultaneous x-ray spectrometers can index up to 60 specimens in turn into the measurement position and for each collect count data for up to 30 elements and read out the analytical results in 1--4 min-all corrected for absorption-enhancement and particle-size or surface-texture effects and wholly unattended. Sample preparation has long been the time-limiting step in x-ray spectrochemical analysis. Second, energy-dispersive spectrometry, in 1970 only beginning to assume its place among instrumental analytical methods, has undergone phenomenal development and application and, some believe, may supplant wavelength spectrometry for most applications in the foreseeable future.

This book was released on 2013-06-29 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface physics and chemistry have in recent years become one of the most active fields in solid state research. A number of techniques have been developed, and both the experimental aspect and the correlated theory are evolving at an extremely fast rate. Electron and ion spectroscopy are of major importance in this development. In this volume, which contains edited and extended versions of eight sets of lectures given at the NATO Advanced Study Institute held at Ghent, Belgium, from August 29 to September 9, 1977, a re view of the state of the art in these fields is given from both an experimental and a theoretical point of view. Electron emission techniques such as UPS (ultraviolet photoemission spectroscopy), XPS (x-ray photoemission spectroscopy), and AES (Auger electron spectroscopy) constitute the major part of this volume, reflecting the fact that they continue to be the most widely applied surface techniques. Recent developments in the application of synchrotron radiation to angle-resolved photoelectron spectroscopy are extensively covered, from an experimental point of view by Prof. W. E. Spicer (Stanford University, U.S.A.) and from a theoretical point of view by Dr. A. Liebsch (Kernforschungsanlage Julich, Germany). Emphasis is put on the study of energy bands in layered structures, and on chemisorption on well-defined surfaces. Chemisorption and catalysis on metals is treated in detail by Prof. G. Ertl (Universitat Munchen, Germany). This chapter contains a review of the application of the different surface techniques to specific surface systems.
