Download or read book Theoretical Treatment of Electron Emission and Related Phenomena written by Benjamin Seznec and published by Springer Nature. This book was released on 2022-06-14 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces readers to the physics governing electron emission under high voltages and temperatures, and highlights recent modeling and numerical developments for describing these phenomena. It begins with a brief introduction, presenting several applications that have driven electron emission research in the last few decades. The authors summarize the most relevant theories including the physics of thermo-field electron emission and the main characteristic parameters. Based on these theories, they subsequently describe numerical multi-physics models and discuss the main findings on the effect of space charges, emitter geometry, pulse duration, etc. Beyond the well-known photoelectric effect, the book reviews recent advanced theories on photon-metal interaction. Distinct phenomena occur when picosecond and femtosecond lasers are used to irradiate a surface. Their consequences on metal electron dynamics and heating are presented and discussed, leading to various emission regimes – in and out of equilibrium. In closing, the book reviews the effects of electron emission on high-voltage operation in vacuum, especially breakdown and conditioning, as the most common examples. The book offers a uniquely valuable resource for graduate and PhD students whose work involves electron emission, high-voltage holding, laser irradiation of surfaces, vacuum or discharge breakdown, but also for academic researchers and professionals in the field of accelerators and solid state physics with an interest in this highly topical area.
Download or read book Electron Scattering in Solid Matter written by Jan Zabloudil and published by Springer Science & Business Media. This book was released on 2005-12-12 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing graduate students and researchers, this book gives a very detailed theoretical and computational description of multiple scattering in solid matter. Particular emphasis is placed on solids with reduced dimensions, on full potential approaches and on relativistic treatments. For the first time approaches such as the screened Korringa-Kohn-Rostoker method are reviewed, considering all formal steps such as single-site scattering, structure constants and screening transformations, and also the numerical point of view. Furthermore, a very general approach is presented for solving the Poisson equation, needed within density functional theory in order to achieve self-consistency. Special chapters are devoted to the Coherent Potential Approximation and to the Embedded Cluster Method, used, for example, for describing nanostructured matter in real space. In a final chapter, physical properties related to the (single-particle) Green's function, such as magnetic anisotropies, interlayer exchange coupling, electric and magneto-optical transport and spin-waves, serve to illustrate the usefulness of the methods described.

Book excerpt: PREFACE. THE Author of this very practical treatise on Scotch Loch - Fishing desires clearly that it may be of use to all who had it. He does not pretend to have written anything new, but to have attempted to put what he has to say in as readable a form as possible. Everything in the way of the history and habits of fish has been studiously avoided, and technicalities have been used as sparingly as possible. The writing of this book has afforded him pleasure in his leisure moments, and that pleasure would be much increased if he knew that the perusal of it would create any bond of sympathy between himself and the angling community in general. This section is interleaved with blank shects for the readers notes. The Author need hardly say that any suggestions addressed to the case of the publishers, will meet with consideration in a future edition. We do not pretend to write or enlarge upon a new subject. Much has been said and written-and well said and written too on the art of fishing but loch-fishing has been rather looked upon as a second-rate performance, and to dispel this idea is one of the objects for which this present treatise has been written. Far be it from us to say anything against fishing, lawfully practised in any form but many pent up in our large towns will bear us out when me say that, on the whole, a days loch-fishing is the most convenient. One great matter is, that the loch-fisher is depend- ent on nothing but enough wind to curl the water, -and on a large loch it is very seldom that a dead calm prevails all day, -and can make his arrangements for a day, weeks beforehand whereas the stream- fisher is dependent for a good take on the state of the water and however pleasant and easy it may be for one living near the banks of a good trout stream or river, it is quite another matter to arrange for a days river-fishing, if one is looking forward to a holiday at a date some weeks ahead. Providence may favour the expectant angler with a good day, and the water in order but experience has taught most of us that the good days are in the minority, and that, as is the case with our rapid running streams, -such as many of our northern streams are, -the water is either too large or too small, unless, as previously remarked, you live near at hand, and can catch it at its best. A common belief in regard to loch-fishing is, that the tyro and the experienced angler have nearly the same chance in fishing, -the one from the stern and the other from the bow of the same boat. Of all the absurd beliefs as to loch-fishing, this is one of the most absurd. Try it. Give the tyro either end of the boat he likes give him a cast of ally flies he may fancy, or even a cast similar to those which a crack may be using and if he catches one for every three the other has, he may consider himself very lucky. Of course there are lochs where the fish are not abundant, and a beginner may come across as many as an older fisher but we speak of lochs where there are fish to be caught, and where each has a fair chance. Again, it is said that the boatman has as much to do with catching trout in a loch as the angler. Well, we dont deny that. In an untried loch it is necessary to have the guidance of a good boatman but the same argument holds good as to stream-fishing...

Download or read book The Expanding Universe written by Sir Arthur Stanley Eddington and published by Cambridge University Press. This book was released on 1987 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This classic book, long out of print, investigates the experimental determination of one of the fundamental constants of astrophysics and its significance for astronomy. The equations of general relativity include a constant lambda in their solution. If lambda is non-zero and positive, this represents the existence of a phenomenon of cosmical repulsion. In this book Eddington discussed the implications of this for models of the universe. The book offers a unique sidelight upon the history of ideas and Eddington's artistry. His evident enjoyment of writing and exposition shine through, and astrophysicists and historians of science will find that this reissue throws fascinating light on one of Britain's greatest scientists.

This book was released on 2017-09-15 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Theory of Electrons and Its Applications to the Phenomena of Light and Radiant Heat: A Course of Lectures Delivered in Columbia University, New York, in March and April 1906 The publication of these lectures, which I delivered in Columbia University in the spring of 1906, has been unduly delayed, chiefly on account of my wish to give some further development to the sub ject, so as to present it in a connected and fairly complete form; for this reason I have not refrained from making numerous additions. Nevertheless there are several highly interesting questions, more or less belonging to the theory of electrons, which I could but slightly touch, upon. I could no more than allude in a note to Voigt's Treatise on magneto-optical phenomena, and neither Planck's views on radiation, nor Einstein's. Principle of relativity have received an adequate treatment. In one other respect this book will, I fear, be found very deficient. No space could be spared for a discussion of the different ways in which the fundamental principles maybe established, so that, for ln. Stance, there was no opportunity to mention the important share that has been taken in the development of the theory by Larmor and Wiechert. It is with great pleasure that I express my thanks to Professor A. P. Wills for his kindness in reading part of the proofs, and to the publisher for the care he has bestowed on my work.

Book excerpt: This extensively updated new edition of the widely acclaimed Treatise on Geochemistry has increased its coverage beyond the wide range of geochemical subject areas in the first edition, with five new volumes which include: the history of the atmosphere, geochemistry of mineral deposits, archaeology and anthropology, organic geochemistry and analytical geochemistry. In addition, the original Volume 1 on "Meteorites, Comets, and Planets" was expanded into two separate volumes dealing with meteorites and planets, respectively. These additions increased the number of volumes in the Treatise from 9 to 15 with the index/appendices volume remaining as the last volume (Volume 16). Each of the original volumes was scrutinized by the appropriate volume editors, with respect to necessary revisions as well as additions and deletions. As a result, 27% were republished without major changes, 66% were revised and 126 new chapters were added. In a many-faceted field such as Geochemistry, explaining and understanding how one sub-field relates to another is key. Instructors will find the complete overviews with extensive cross-referencing useful additions to their course packs and students will benefit from the contextual organization of the subject matter Six new volumes added and 66% updated from 1st edition. The Editors of this work have taken every measure to include the many suggestions received from readers and ensure comprehensiveness of coverage and added value in this 2nd edition The esteemed Board of Volume Editors and Editors-in-Chief worked cohesively to ensure a uniform and consistent approach to the content, which is an amazing accomplishment for a 15-volume work (16 volumes including index volume)!

Download or read book The Spectroscope written by Richard A. Proctor and published by Forgotten Books. This book was released on 2017-10-24 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Spectroscope: And Its Work Spectroscopic Analysis clear and simple for beginners, but at the same time accurate, and as complete as pos sible within so limited a space - following, in this respect, the plan already adopted in my elementary treatises on Astronomy and Physical Geography. In order to make room for subjects properly belonging to Spectroscopy, several subjects which are very fully treated of in large works on the Spectroscope (and indeed in one not containing more letterpress than the present) have been dealt with very briefly. It seems to me that - to mention but one such subject - full accounts of the various contrivances for obtaining in tense heat and light, such as that with which Schellen occupies the first fifty-two pages of his treatise on Spectrum Analysis, are unsuitable even for large works intended for the general student, and are altogether out of place in an elementary treatise, necessarily limited in size. I doubt, indeed, whether anything can be usefully said in textbooks respecting details of the con struction of instruments which the observer (who alone could profit by such explanations) must possess and employ. A few minutes devoted to the examination of the instrument itself will, in such a case, be of more use than many hours' study of textbook explanations. On the other hand, I have endeavoured to give a full account of all the principles on which the application of Spectroscopy depends, as also of all the chief methods of observation and then results. I am greatly indebted to Mr. J. Browning, the emi nent Optician, for the use of many cuts illustrating various forms of Spectroscopes, and their adjuncts.

Download or read book J J Thompson And The Discovery Of The Electron written by E. A. Davis and published by CRC Press. This book was released on 2002-09-11 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This historical survey of the discovery of the electron has been published to coincide with the centenary of the discovery. The text maps the life and achievements of J.J. Thomson, with particular focus on his ideas and experiments leading to the discovery. It describes Thomson's early years and education. It then considers his career at Cambridge, first as a fellow of Trinity, later as the head of the Cavendish Laboratory and finally as Master of Trinity and national spokesman for science. The core of the book is concerned with the work undertaken at the Cavendish, culminating in the discovery of "corpuscles", later named "electrons".; In the final two chapters, the immediate aftermath and implications of the work are described. These include the creation of the subject of atomic physics as well as the broader long term developments which can be traced from vacuum valves and the transistor through to the microelectronics revolution.
