Available in PDF, EPUB and Kindle. Book excerpt: Significant progress has been made in producing large area, heteroepitaxial diamond films. Work has been directed at heteroepitaxial nucleation of diamond on nickel in a hot-filament chemical vapor deposition (CVD) reactor; and high rate, textured growth in a flat flame acetylene combustion reactor. In addition, a detailed kinetic model of the combustion reactor has been developed and validated by gas microprobe sampling. Comparisons of model predictions and experimental observations of growth rate and morphology have been used to develop a lull understanding of the deposition process. Future studies will begin examining dopant effects on the diamond nucleation and growth process.

Available in PDF, EPUB and Kindle. Book excerpt: Diamond has exceptional semiconducting and optical properties that can be used for a wide variety of new applications such as high temperature, high power devices, and optical windows. Exploitation of these properties of diamond needs the development of heteroepitaxial diamond growth process on traditional substrates such as Silicon and Silicon Carbide. Bias enhanced nucleation (BEN) followed by Plasma Enhanced Chemical vapor Deposition (PECVD) has been recognized as a promising route to achieve this goal. However, the BEN process for heteroepitaxy and its mechanism is not well understood. In this study, a system is designed and fabricated to enable the application of bias during diamond deposition in an ASTEX PECVD system, and heteroepitaxial diamond films are grown. The evolution of the oriented diamond film and its microstructure is studied by SEM, TEM, and XRD techniques revealing the formation of misoriented grains, extensive twinning and low angle grain boundaries. The effect of the BEN process conditions on the degree of orientation is investigated. It is observed that the orientation of the films improved at lower bias durations, methane flow rates and bias voltages. TEM images of the nucleation layer are analyzed, and the changes in the nucleation layer grain structure with process parameters are studied. Significant variation in the microstructure and grain size from an average of about 560 nm to about 10 nm is observed with change in process conditions. The BEN process is investigated and the nature of the deposit forming during this step is revealed using SEM, TEM and Raman spectroscopy to be predominantly a nanocrystalline diamond film along with rhombohedral and amorphous carbon. A simple model based on the formation of a nanocrystalline diamond particles during BEN, followed by their growth and coalescence under the plasma is proposed to describe the oriented film formation. The variations in microstructures and orientation are correlated with the process conditions under which they are formed.

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.

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.
Download or read book The Physics of Diamond written by Società italiana di fisica and published by IOS Press. This book was released on 1997 with total page 635 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diamond is an extreme material among possible atomic aggregations in nature, and as such has many extreme properties. This unique position makes it a fascinating subject both for science and for applications. This has been particularly true in recent years, since the surprising discovery at Union Carbide (1953) of the possibility of chemical vapour deposition of diamond films at low pressures, where diamond is metastable with respect to graphite. This discovery cleared the way to the development of economical deposition techniques that have been obtaining progressively better-quality diamond, both pure and doped, in a controlled way and for a variety of applications. The remarkable properties and applications range from mechanical (the extreme hardness, tensile and compressive strength, wear performance) to thermal (the highest conductivity), optical (wide range of transparency), chemical (inertness to most chemicals), biological (biocompatibility) and electronic (high electronic carrier mobility, large band gap and dielectric breakdown strength, negative electron affinity), with the simultaneous presence of so many extraordinary qualities often resulting in added value for a given application.We are presently at a turning point in the development of diamond physics and applications. While some achievements can be considered well established, on the other hand, new opportunities and challenges are facing the scientific community, particularly with regard to novel exciting deposition processes and techniques or new properties and applications in electronics. This Enrico Fermi Course on "The Physics of Diamond" is particularly focused on the new developments and prospects, which may well constitute a reference point for a new generation of scientists at what may possibly be the beginning of a new age in diamond. The course attracted several of the most distinguished experts in the field as lecturers and an audience of almost as distinguished students and observers from 19 countries. Participation and discussions were lively to the very last day, ranging from traditional diamond physics to new diamond physics, and from well-known applications to the new exciting opportunities.The material in this volume is organized in the following way: the first part (13 lectures) is essentially devoted to growth and structure, the second part to properties and applications, with a closing lecture exploring new exotic diamonds in the distant future. The earlier lectures extensively cover the many processes of plasma chemical vapour deposition, including advanced contributions in theoretical modelling of these processes. Novel deposition mechanisms are considered: low-temperature CVD and laser-activated processes, including the so-called QQC experiments. This first part closes with a discussion of amorphous phases. In the second part, particular emphasis is placed on electronic properties and applications. This includes an extensive discussion of doping and, in addition, the promising perspectives of diamond as an electron emitter. Its newly discovered remarkable electron affinity properties lead to a new dimension in research and development, of great strategical importance for an increasing role of diamond in electronics.
