This book was released on 2003-12-31 with total page 781 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume deals with the basic knowledge and understanding of fundamental interactions of low energy electrons with molecules. It pro vides an up-to-date and comprehensive account of the fundamental in teractions of low-energy electrons with molecules of current interest in modern technology, especially the semiconductor industry. The primary electron-molecule interaction processes of elastic and in elastic electron scattering, electron-impact ionization, electron-impact dissociation, and electron attachment are discussed, and state-of-the art authoritative data on the cross sections of these processes as well as on rate and transport coefficients are provided. This fundamental knowledge has been obtained by us over the last eight years through a critical review and comprehensive assessment of "all" available data on low-energy electron collisions with plasma processing gases which we conducted at the National Institute of Standards and Technology (NIST). Data from this work were originally published in the Journal of Physical and Chemical Reference Data, and have been updated and expanded here. The fundamental electron-molecule interaction processes are discussed in Chapter 1. The cross sections and rate coefficients most often used to describe these interactions are defined in Chapter 2, where some recent advances in the methods employed for their measurement or calculation are outlined. The methodology we adopted for the critical evaluation, synthesis, and assessment of the existing data is described in Chapter 3. The critically assessed data and recommended or suggested cross sections and rate and transport coefficients for ten plasma etching gases are presented and discussed in Chapters 4, 5, and 6.

This book was released on 2012-12-06 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a short outline of the present state of the theory of electron collisions with atomic particles - atoms, molecules and ions. It is addressed to those who by nature of their work need detailed information about the cross sections of various processes of electron collisions with atomic particles: experimentalists working in plasma physics, optics, quantum electronics, atmospheric and space physics, 'etc. Some of the cross sections have been measured. But in many important cases the only source of information is theoretical calcu lation. The numerous theoretical papers dealing with electronic collision processes contain various approximations. The inter relation between them and the level of their accuracy is often diffi cult to understand without a systematic study of the theory of atomic collisions, not to mention that theoretical considerations are necessary for the consistent interpretation of experimental results. The main constituents of the book are: 1. General theory with special emphasis on the topics most impor tant for understanding and discussing electron collisions with atomic particles.

This book was released on 1965 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This final report contains a discussion of the experimental and analytical studies of electron attachment and detachment in pure O2, in O2-CO2 mixtures, and in O2-H2O mixtures. Measured values of attachment and detachment coefficients and equilibrium constants are tabulated. The results of improved measurements of thermal attachment coefficients and thermal electron mobilities are presented and used to obtain an improved value for the electron affinity for O2 of 0.43+0.02 ev. The present state of the studies of electron attachment and detachment in O2-O mixtures is discussed. The results of the studies of electron-molecular ion recombination in N2,O2, and O2, and NO which have been carried out under this contract are given along with a summary of our previous measurements. The results of a determination of momentum transfer and inelastic collision cross sections for electrons in N2 are summarized. Preliminary results of a determination of electron scattering cross sections in O2 are given and are used to discuss the behavior of electrons in air. (Author).

This book was released on 1969 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rate coefficient for the two-body attachment to O3 of 300K electrons has been measured. The attachment coefficient increases rapidly with increasing electron energy at characteristic electron energies of 0.3 eV. Measurements in pure O3 also show that the attachment process is directly porportional to pressure for pressures between 0.5 and 2 Torr, as expected for a dissociative attachment process. Unsuccessful attempts to detect electron detachment in collisions of O3( - ) and CO3( - ) with O3 suggest an upper limit to the rate coefficient for this process. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: In fuel cell research, the gap between fundamental electrochemical processes and the engineering of fuel cell systems is bridged by the physical modelling of fuel cells. This relatively new discipline aims to understand the basic transport and kinetic phenomena in a real cell and stack environment, paving the way for improved design and performance. The author brings his unique approach to the analytical modeling of fuel cells to this essential reference for energy technologists. Covers recent advances and analytical solutions to a range of problems faced by energy technologists, from catalyst layer performance to thermal stability Provides detailed graphs, charts and other tools (glossary, index) to maximize R&D output while minimizing costs and time spent on dead-end research Presents Kulikovsky’s signature approach (and the data to support it)—which uses "simplified" models based on idealized systems, basic geometries, and minimal assumptions—enabling qualitative understanding of the causes and effects of phenomena

Available in PDF, EPUB and Kindle. Book excerpt: Electron-Molecule Interactions and Their Applications, Volume 1 presents a comprehensive account of electron-molecule interactions in high- and ultra-high-pressure gases and liquids. Topics covered include elastic scattering of electrons by molecules; excitation, ionization, and dissociation of molecules by electron impact; electron-molecule resonances; and electron attachment and detachment processes. This volume is comprised of seven chapters and begins with a discussion on non-resonant elastic scattering and rotational excitation of molecules by electrons, followed by a review of non-resonant vibrational and electronic excitation. The reader is then introduced to resonance effects in electron scattering; electron-induced ionization and dissociation of molecules; and electron-molecule resonances. The ionization mechanisms and types of ions produced are highlighted, along with differential ionization cross sections. The final two chapters focus on electron attachment and detachment processes, paying particular attention to modes of electron capture by molecules such as via negative-ion resonant states. The collisional dynamics for a few selected atomic reactants are also described. Physicists will find this book extremely helpful.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Theory of Ionization of Gases by Collision After studying the changes which take place in the conductivity of gases through which ions are passing under various conditions, I was led to propose the theory of ionization by collision to explain the development of currents in gases. The accuracy of the theory has been established by a large number of experiments specially arranged to measure conductivities which could be compared with the values obtained from theoretical considerations. The researches have brought to light the fact that ionization by collision takes place when comparatively small potential differences are established between electrodes in a gas at a suitable pressure, so that considerable multiplication of the ions may be obtained by this process with forty or fifty volts, and consequently with comparatively small velocities of the ions. This is in marked contrast with the previously known cases of ionization produced by the motion of ions through a gas, where the velocity is always very high, sometimes approaching that of light. Such, for instance, is the case for the negative particles emitted by radioactive substances, or for the particles composing the cathode rays and the Lenard rays when the ions move with velocities that are acquired under the action of some thousands of volts.

This book was released on 2013-11-11 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers collected in this volume have been presented during a workshop on "Electron-Atom and Molecule Collisions" held at the Centre for Interdisciplinary Studies of the University of Bielefeld in May 1980. This workshop, part of a larger program concerned with the "Properties and Reactions of Isolated Molecules and Atoms," focused on the theory and computational techniques for the quanti tative description of electron scattering phenomena. With the advances which have been made in the accurate quantum mechanical characterisation of bound states of atoms and molecules, the more complicated description of the unbound systems and resonances important in electron collision processes has matured too. As expli cated in detail in the articles of this volume, the theory for the quantitative explanation of elastic and inelastic electron molecule collisions, of photo- and multiple photon ionization and even for electron impact ionization is well developed in a form which lends itself to a complete quantitative ab initio interpretation and pre diction of the observable effects. Many of the experiences gained and the techniques which have evolved over the years in the com putational characterization of bound states have become an essential basis for this development. To be sure, much needs to be done before we have a complete and detailed theoretical understanding of the known collisional processes and of the phenomena and effects, which may still be un covered with the continuing refinement of the experimental tech niques.
