This book gives an overview of modern cathodes and electron emitters for vacuum tubes and vacuum electron devices in general. It covers the latest developments in field emission theory as well as new methods towards improving thermionic and cold cathodes. It addresses thermionic cathodes, such as oxide cathodes, impregnated and scandate cathodes, as well as photocathodes and field emitters – the latter comprising carbon nanotubes, graphene and Spindt-type emitter arrays. Despite the rise and fall of the once dominant types of vacuum tubes, such as radio valves and cathode ray tubes, cathodes are continually being improved upon as new applications with increased demands arise, for example in electron beam lithography, high-power and high-frequency microwave tubes, terahertz imaging and electron sources for accelerators. Written by 17 experts in the field, the book presents the latest developments in cathodes needed for these applications, discussing the state of the art and addressing future trends.

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.

Low beam energies have been implemented in a simplified SEM technique; where the electron source, remote in standard SEMs, is brought within tens of nanometers to the object. This method, known as the "near field emission scanning electron microscopy" (NFESEM), is capable of imaging conducting surfaces with nanometer resolution using beam energies less than 60 eV. The terminology "near" refers to the locality of the field-emitted electron source; which is to distinguish itself from the "remote" field emission gun sources used in standard SEMs. The main aim of this instrument is the realization of some kind of surface topography image due to the exposure of a primary beam of electrons, as it is rastered along the sample surface. This will be achieved by two distinct (although related) experiments: measuring the field emission (FE) current while scanning and detecting the secondary electrons (SE)s generated when the electron beam impinges on the surface. Here, the FE properties, in accordance with the tip-sample separation, will be emphasized, since the variations in SE yield are directly proportional to the impinging primary electron beam. We observe a direct correlation between the image contrast and the FE current, where the image is enhanced with increasing FE current. Moreover, simple electrostatic measurements can be used to define the performance of the device.

Flat Panel Displays (FPDs) are a frequent feature in our daily lives, used in mobile phones, laptop computers, desktop computer monitors and TVs. Several display technologies have been developed for FPDs, such as liquid crystal display (LCD), plasma display panel (PDP), light emitting diode (LED), organic light emitting device (OLED) and field emission display (FED). Introduction to Flat Panel Displays describes the fundamental sciences behind each display technology: LCD, PDP, LED, OLED and FED including carbon nanotubes. It contains a comparative analysis of the different display technologies in which detailed overviews of each technology are linked together so as to provide a comprehensive reference for students and display engineers, alike. Solved problems as well as homework problems are provided in each chapter to help consolidate students’ reading, as well as solutions hosted on an accompanying website. Features include: the classifications and specifications of display technologies as guidelines for developing a display and judging their performances; principles for designing color displays with good color saturation and wide color gamut; basic operating principles of thin-film transistors (TFTs) and their applications to state-of-the-art TFT-LCD and TFT-OLED; an overview of FED fundamentals comprising the physics of field emission, as well as FED structure and display mechanism. Senior undergraduate and graduate students taking courses in engineering, physics and chemistry will benefit from the systematic approach used throughout the book, which will help to prepare students for entry into a display profession. Display engineers, research scientists and technicians working on the development of flat panel display technology will also find this book an invaluable resource. Comparisons of the strengths and weaknesses of each of the display technologies will help professionals to decide which to use for their applications. The Society for Information Display (SID) is an international society, which has the aim of encouraging the development of all aspects of the field of information display. Complementary to the aims of the society, the Wiley-SID series is intended to explain the latest developments in information display technology at a professional level. The broad scope of the series addresses all facets of information displays from technical aspects through systems and prototypes to standards and ergonomics
