Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Volume 2 of the book begins with chapter 6, in which we have taken up conventional MWTs (such as TWTs, klystrons, including multi-cavity and multi-beam klystrons, klystron variants including reflex klystron, IOT, EIK, EIO and twystron, and crossed-field tubes, namely, magnetron, CFA and carcinotron). In chapter 7, we have taken up fast-wave tubes (such as gyrotron, gyro-BWO, gyro-klystron, gyro-TWT, CARM, SWCA, hybrid gyro-tubes and peniotron). In chapter 8, we discuss vacuum microelectronic tubes (such as klystrino module, THz gyrotron and clinotron BWO); plasma-assisted tubes (such as PWT, plasma-filled TWT, BWO, including PASOTRON, and gyrotron); and HPM (high power microwave) tubes (such as relativistic TWT, relativistic BWO, RELTRON (variant of relativistic klystron), relativistic magnetron, high power Cerenkov tubes including SWO, RDG or orotron, MWCG and MWDG, bremsstrahlung radiation type tube, namely, vircator, and M-type tube MILO). In Chapter 9, we provide handy information about the frequency and power ranges of common MWTs, although more such information is provided at relevant places in the rest of the book as and where necessary. Chapter 10 is an epilogue that sums up the authors' attempt to bring out the various aspects of the basics of and trends in high power MWTs.
Download or read book GaN and Related Alloys 1999 Volume 595 written by Thomas H. Myers and published by . This book was released on 2000-05-05 with total page 1070 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book on gallium nitride (GaN) and associated materials focuses on advances in basic science, as well as the rapidly maturing technologies involving blue/green light emitters, detectors and high-power electronics. A highlight is a report on wide-bandgap semiconductor research done in Europe. Also reported is the commercialization of a laser operating at 405nm wavelength with a 4000-hour device lifetime. At 450nm emission wavelength, significant reductions in lifetime were found, and are believed to arise from nonideal properties of the InGaN alloy used in the active layer of the device. Additional topics include: the significant success of transistors for microwave applications; improvements in the epitaxy of GaN, using both selective area growth techniques (lateral epitaxy overgrowth) and introducing low-temperature intralayers in the films; advances in both molecular beam epitaxy and metal-organic vapor phase epitaxy, including several studies of quantum dot formation in strained alloys and improvements in hydride vapor phase epitaxy, particularly for providing very thick films.

Available in PDF, EPUB and Kindle. Book excerpt: Ultrananocrystalline Diamond: Synthesis, Properties, and Applications is a unique practical reference handbook. Written by the leading experts worldwide it introduces the science of UNCD for both the R&D community and applications developers using UNCD in a diverse range of applications from macro to nanodevices, such as energy-saving ultra-low friction and wear coatings for mechanical pump seals and tools, high-performance MEMS/NEMS-based systems (e.g. in telecommunications), the next generation of high-definition flat panel displays, in-vivo biomedical implants, and biosensors. This work brings together the basic science of nanoscale diamond structures, with detailed information on ultra-nanodiamond synthesis, properties, and applications. The book offers discussion on UNCD in its two forms, as a powder and as a chemical vapor deposited film. Also discussed are the superior mechanical, tribological, transport, electrochemical, and electron emission properties of UNCD for a wide range of applications including MEMS/ NEMS, surface acoustic wave (SAW) devices, electrochemical sensors, coatings for field emission arrays, photonic and RF switching, biosensors, and neural prostheses, etc. Ultrananocrystalline Diamond summarises the most recent developments in the nanodiamond field, and presents them in a way that will be useful to the R&D community in both academic and corporate sectors Coverage of both nanodiamond particles and films make this a valuable resource for both the nanotechnology community and the field of thin films / vacuum deposition Written by the world’s leading experts in nanodiamond, this second edition builds on its predecessor’s reputation as the most up-to-date resource in the field

Download or read book Ultrathin Carbon Based Overcoats for Extremely High Density Magnetic Recording written by Reuben Jueyuan Yeo and published by Springer. This book was released on 2017-06-20 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest research in ultrathin carbon-based protective overcoats for high areal density magnetic data storage systems, with a particular focus on hard disk drives (HDDs) and tape drives. These findings shed new light on how the microstructure and interfacial chemistry of these sub-20 nm overcoats can be engineered at the nanoscale regime to obtain enhanced properties for wear, thermal and corrosion protection – which are critical for such applications. Readers will also be provided with fresh experimental insights into the suitability of graphene as an atomically-thin overcoat for HDD media. The easy readability of this book will appeal to a wide audience, ranging from non-specialists with a general interest in the field to scientists and industry professionals directly involved in thin film and coatings research.

Available in PDF, EPUB and Kindle. Book excerpt: One of the goals of materials science is to design alloys with pre-specified desirable technological properties. To achieve this goal, it is necessary to have a thorough understanding of the fundamental mechanisms underlying materials behavior. In particular, one must understand the effects on alloy properties caused by intentional changes in concentration and how the combinations of temperature, time and uncontrollable foreign impurities affect microstructure. In addition to the equilibrium phase information contained in phase diagrams, nonequilibrium dynamic processes and metastable phases are known to be crucial in determining materials properties. This volume brings together researchers working on various aspects of nonequilibrium processes in materials to discuss current research issues and to provide guidelines for future work. Particular attention was paid to understanding particle nucleation and growth, both experimentally and theoretically, solid-state reactions, nanosystems, liquid-solid transformations, and solidification and amorphization. On the theoretical side, fundamental principles governing nucleation and growth, and related phenomena such as coarsening and Ostwald ripening, are discussed. Progress is also reported on the phase field method and on Monte Carlo simulations.
