Available in PDF, EPUB and Kindle. Book excerpt: Diamond film growth by chemical vapor deposition (CVD) has burgeoned rapidly during the past decade, accompanied by considerable progress in fundamental understanding. Particular progress has been made in understanding chemistry taking place in the gas phase above the substrate and in identification of the precuror(s) primarily responsible for growth, but the details of reactions taking place on the growing surface are as yet unknown. However, despite the commercial importance of high growth rates and the potential for gaining insight into the details of the growth mechanism, only a handful of studies of the growth kinetics of polycrystalline diamond films have been reported.

This book was released on 1992 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growth rates of homoepitaxial (110), (111), and (100) diamond films were experimentally determined, for the first time, in a hot filament reactor using methane and carbon tetrachloride as the carbon source. Methane concentrations from 0.07% to 1.03% in H2 were studied at a subsum temperature of 970 'C. Growth ran were found to be crystal-face dependent with respect to methane concentration, being linear or first order for the (100) orientation, sublinear for (110), and sigmoidal for (111). The observed growth kinetics of (111) suggest the viability of an acetylene mechanism for (111), along with the methyl radical mechanism at methane concentrations above 0.73%. CC14 concentrations from 0.06% to 0.69% in H2 were also investigated at a substrate temperature of 970 C. Growth rate behavior was similar to that of methane for all three crystal faces. The temperature dependence of the growth rates was also crystal-orientation dependent. At subsum temperatures above 730 C, growth rates are thought to be mainly transport limited, yielding effective activation energies of 8+/-3, 18 + or - 2, and 12+ or - 4 kcal/mol for (100), (110), and (111) orientations, respectively. At substrate temperatures below 730 C, growth rates are thought to be surface reaction rate-limited, with an overall effective activation energy of 50 + or -19 kcal/mol for the three crystal-orientations studied.

Download or read book Thin Film Diamond I written by Christopher Nebel and published by Academic Press. This book was released on 2003-12-12 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews the state of the art of thin film diamond, a very promising new semiconductor that may one day rival silicon as the material of choice for electronics. Diamond has the following important characteristics; it is resistant to radiation damage, chemically inert and biocompatible and it will become "the material" for bio-electronics, in-vivo applications, radiation detectors and high-frequency devices. Thin-Film Diamond is the first book to summarize state of the art of CVD diamond in depth. It covers the most recent results regarding growth and structural properties, doping and defect characterization, hydrogen in and on diamond as well as surface properties in general, applications of diamond in electrochemistry, as detectors, and in surface acoustic wave devices. · Accessible by both experts and non-experts in the field of semi-conductors research and technology, each chapter is written in a tutorial format· Helping engineers to manufacture devices with optimized electronic properties· Truly international, this volume contains chapters written by recognized experts representing academic and industrial institutions from Europe, Japan and the US
Download or read book Diamond Electronic Properties and Applications written by Lawrence S. Pan and published by Springer Science & Business Media. This book was released on 2013-11-27 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of diamond for electronic applications is not a new idea. As early as the 1920's diamonds were considered for their use as photoconductive detectors. However limitations in size and control of properties naturally limited the use of diamond to a few specialty applications. With the development of diamond synthesis from the vapor phase has come a more serious interest in developing diamond-based electronic devices. A unique combination of extreme properties makes diamond partiCularly well suited for high speed, high power, and high temperature applications. Vapor phase deposition of diamond allows large area films to be deposited, whose properties can potentially be controlled. Since the process of diamond synthesis was first realized, great progress have been made in understanding the issues important for growing diamond and fabricating electronic devices. The quality of both intrinsic and doped diamond has improved greatly to the point that viable applications are being developed. Our understanding of the properties and limitations has also improved greatly. While a number of excellent references review the general properties of diamond, this volume summarizes the great deal of literature related only to electronic properties and applications of diamond. We concentrate only on diamond; related materials such as diamond-like carbon (DLC) and other wide bandgap semiconductors are not treated here. In the first chapter Profs. C. Y. Fong and B. M. Klein discuss the band structure of single-crystal diamond and its relation to electronic properties.

Book excerpt: Discusses the most advanced techniques for diamond growth Assists diamond researchers in deciding on the most suitable process conditions Inspires readers to devise new CVD (chemical vapor deposition Ever since the early 1980s, and the discovery of the vapour growth methods of diamond film, heteroexpitaxial growth has become one of the most important and heavily discussed topics amongst the diamond research community. Kobashi has documented such discussions with a strong focus on how diamond films can be best utilised as an industrial material, working from the premise that crystal diamond films can be made by chemical vapour disposition. Kobashi provides information on the process and characterization technologies of oriented and heteroepitaxial growth of diamond films.
Download or read book Crystal Growth Technology written by K. Byrappa and published by Springer Science & Business Media. This book was released on 2003-04-17 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crystals are the unacknowledged pillars of modern technology. The modern technological developments depend greatly on the availability of suitable single crystals, whether it is for lasers, semiconductors, magnetic devices, optical devices, superconductors, telecommunication, etc. In spite of great technological advancements in the recent years, we are still in the early stage with respect to the growth of several important crystals such as diamond, silicon carbide, PZT, gallium nitride, and so on. Unless the science of growing these crystals is understood precisely, it is impossible to grow them as large single crystals to be applied in modern industry. This book deals with almost all the modern crystal growth techniques that have been adopted, including appropriate case studies. Since there has been no other book published to cover the subject after the Handbook of Crystal Growth, Eds. DTJ Hurle, published during 1993-1995, this book will fill the existing gap for its readers. The book begins with "Growth Histories of Mineral Crystals" by the most senior expert in this field, Professor Ichiro Sunagawa. The next chapter reviews recent developments in the theory of crystal growth, which is equally important before moving on to actual techniques. After the first two fundamental chapters, the book covers other topics like the recent progress in quartz growth, diamond growth, silicon carbide single crystals, PZT crystals, nonlinear optical crystals, solid state laser crystals, gemstones, high melting oxides like lithium niobates, hydroxyapatite, GaAs by molecular beam epitaxy, superconducting crystals, morphology control, and more. For the first time, the crystal growth modeling has been discussed in detail with reference to PZT and SiC crystals.
