Carbon forms a variety of allotropes due to the diverse hybridization of s- and p-electron orbitals, including the time-honored graphite and diamond as well as new forms such as C60 fullerene, nanotubes, graphene, and carbyne. The new family of carbon isotopes—fullerene, nanotubes, graphene, and carbyne—is called “nanostructured carbon” or “nanocarbon.” These isotopes exhibit extreme properties such as ultrahigh mechanical strength, ultrahigh charge–carrier mobility, and high thermal conductivity, attracting considerable attention for their electronic and mechanical applications as well as for exploring new physics and chemistry in the field of basic materials science. Electron sources are important in a wide range of areas, from basic physics and scientific instruments to medical and industrial applications. Carbon nanotubes (CNTs) and graphene behave as excellent electron-field emitters owing to their exceptional properties and offer several benefits compared to traditional cathodes. Field emission (FE) produces very intense electron currents from a small surface area with a narrow energy spread, providing a highly coherent electron beam—a combination that not only provides us with the brightest electron sources but also explores a new field of electron beam–related research. This book presents the enthusiastic research and development of CNT-based FE devices and focuses on the fundamental aspects of FE from nanocarbon materials, including CNTs and graphene, and the latest research findings related to it. It discusses applications of FE to X-ray and UV generation and reviews electron sources in vacuum electronic devices and space thrusters. Finally, it reports on the new forms of carbon produced via FE from CNT.

There has been tremendous development in the science of carbon in past years. First came the development of the chemical vapor deposition of diamond, followed by the discovery of a new class of molecules - the fullerenes. Carbon nanotubes were discovered and techniques were developed to deposit new phases of amorphous carbon containing mainly sp3 bonding. This book brings together scientists and engineers from all areas of carbon research, both sp2 and sp3 bonded, from the fully amorphous to nanostructured carbon, to the highly ordered nanotubes. It covers a range of subjects including the synthesis and properties of nanotubes, as well as diamond-like carbon deposition and properties. Applications range from nanotubes for hydrogen storage, to electrochemical double-layer capacitors (supercapacitors), field emission displays, hard coatings, and carbon coatings for magnetic storage technology. The book deals with the growth, characterization, properties and applications of nanotubes and field emission from all varieties of carbon, amorphous and diamond-like carbon- growth, properties and applications. It also contains papers on diamond, silicon carbide, carbon nitride and beryllium films.
