Book Description
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.

Book Description
Modern electronic devices and novel materials often derive their extraordinary properties from the intriguing, complex behavior of large numbers of electrons forming what is known as an electron liquid. This book provides an in-depth introduction to the physics of the interacting electron liquid in a broad variety of systems, including metals, semiconductors, artificial nano-structures, atoms and molecules. One, two and three dimensional systems are treated separately and in parallel. Different phases of the electron liquid, from the Landau Fermi liquid to the Wigner crystal, from the Luttinger liquid to the quantum Hall liquid are extensively discussed. Both static and time-dependent density functional theory are presented in detail. Although the emphasis is on the development of the basic physical ideas and on a critical discussion of the most useful approximations, the formal derivation of the results is highly detailed and based on the simplest, most direct methods.

Book Description
Conquering the Electron offers readers a true and engaging history of the world of electronics, beginning with the discoveries of static electricity and magnetism and ending with the creation of the smartphone and the iPad. This book shows the interconnection of each advance to the next on the long journey to our modern-day technologies. Exploring the combination of genius, infighting, and luck that powered the creation of today's electronic age, Conquering the Electron debunks the hero worship so often plaguing the stories of great advances. Want to know how AT&T’s Bell Labs developed semiconductor technology—and how its leading scientists almost came to blows in the process? Want to understand how radio and television work—and why RCA drove their inventors to financial ruin and early graves? Conquering the Electron offers these stories and more, presenting each revolutionary technological advance right alongside blow-by-blow personal battles that all too often took place.

Book Description
to the Second Edition Since the first (1986) edition of this book, the numbers of installations, researchers, and research publications devoted to electron energy-loss spec troscopy (EELS) in the electron microscope have continued to expand. There has been a trend towards intermediate accelerating voltages and field-emission sources, both favorable to energy-loss spectroscopy, and sev eral types of energy-filtering microscope are now available commercially. Data-acquisition hardware and software, based on personal computers, have become more convenient and user-friendly. Among university re searchers, much thought has been given to the interpretation and utilization of near-edge fine structure. Most importantly, there have been many practi cal applications of EELS. This may reflect an increased awareness of the potentialities of the technique, but in many cases it is the result of skill and persistence on the part of the experimenters, often graduate students. To take account of these developments, the book has been extensively revised (over a period of two years) and more than a third of it rewritten. I have made various minor changes to the figures and added about 80 new ones. Except for a few small changes, the notation is the same as in the first edition, with all equations in SI units.

Book Description
Nearly all of this book is taken from an article prepared for a volume of the Encyclopedia of Physics. This article, in turn, is partly based on Dr. Norbert Rosenzweig's translation of an older article on the same subject, written by one of us (H.A.B.) about 25 years ago for the Geiger-Scheel Handbuch der Physik. To the article written last year we have added some Addenda and Errata. These Addenda and Errata refer back to some of the 79 sections of the main text and contain some misprint corrections, additional references and some notes. The aim of this book is two-fold. First, to act as a reference work on calcu lations pertaining to hydrogen-like and helium-like atoms and their comparison with experiments. However, these calculations involve a vast array of approximation methods, mathematical tricks and physical pictures, which are also useful in the application of quantum mechanics to other fields. In many sections we have given more general discussions of the methods and physical ideas than is necessary for the study of the H- and He-atom alone. We hope that this book will thus at least partly fulfill its second aim, namely to be of some use to graduate students who wish to learn "applied quantum mechanics". A basic knowledge of the principles of quantum mechanics, such as given in the early chapters of Schiff's or Bohm's book, is presupposed.

Book Description
A practical, in-depth description of the physics behind electron emission physics and its usage in science and technology Electron emission is both a fundamental phenomenon and an enabling component that lies at the very heart of modern science and technology. Written by a recognized authority in the field, with expertise in both electron emission physics and electron beam physics, An Introduction to Electron Emission provides an in-depth look at the physics behind thermal, field, photo, and secondary electron emission mechanisms, how that physics affects the beams that result through space charge and emittance growth, and explores the physics behind their utilization in an array of applications. The book addresses mathematical and numerical methods underlying electron emission, describing where the equations originated, how they are related, and how they may be correctly used to model actual sources for devices using electron beams. Writing for the beam physics and solid state communities, the author explores applications of electron emission methodology to solid state, statistical, and quantum mechanical ideas and concepts related to simulations of electron beams to condensed matter, solid state and fabrication communities. Provides an extensive description of the physics behind four electron emission mechanisms—field, photo, and secondary, and how that physics relates to factors such as space charge and emittance that affect electron beams. Introduces readers to mathematical and numerical methods, their origins, and how they may be correctly used to model actual sources for devices using electron beams Demonstrates applications of electron methodology as well as quantum mechanical concepts related to simulations of electron beams to solid state design and manufacture Designed to function as both a graduate-level text and a reference for research professionals Introduction to the Physics of Electron Emission is a valuable learning tool for postgraduates studying quantum mechanics, statistical mechanics, solid state physics, electron transport, and beam physics. It is also an indispensable resource for academic researchers and professionals who use electron sources, model electron emission, develop cathode technologies, or utilize electron beams.

Book Description
In the complex landscape of modern physics, the electron has often been shrouded in a veil of esoteric theories and paradoxical concepts. From wave-particle duality to quantum fields, the scientific community has journeyed through a labyrinth of abstract ideas to grasp the essence of this fundamental particle. ‘Redefining the Electron’ seeks to illuminate a path out of this maze by revisiting and reinterpreting fundamental concepts that govern the behaviour of electrons. Through clear and accessible language, the book dismantles the complexities of quantum mechanics and the standard model, emphasizing that not all phenomena require arcane explanations. By revisiting foundational principles, ‘Redefining the Electron’ endeavours to make sense of the electron’s behaviour in terms that resonate with both seasoned scientists and curious minds. In this book, gravity is reimagined as an emergent property of matter, influenced by the density and alignment of virtual photon lines. This approach not only provides a fresh perspective on gravitational forces but also ties together the phenomena of light propagation and gravitational attraction within a unified framework. In a world where complexity often reigns supreme, ‘Redefining the Electron’ champions a return to fundamental principles. By peeling back the layers of modern physics, it reveals a more elegant and comprehensible picture of the electron, offering a renewed sense of clarity and purpose to the study of physics. This book is a must-read for anyone interested in the frontiers of science and the quest to unravel the mysteries of the universe. It serves as a reminder that sometimes, the most profound insights are found not in the complexities of theory but in the simplicity of fundamental truths.
