This book was released on 2016-06-14 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive introduction to a recently-developed approach to the growth mechanism of thin films and nanostructures via chemical vapour deposition (CVD). Starting from the underlying principles of the low pressure synthesis of diamond films, it is shown that diamond growth occurs not by individual atoms but by charged nanoparticles. This newly-discovered growth mechanism turns out to be general to many CVD and some physical vapor deposition (PVD) processes. This non-classical crystallization is a new paradigm of crystal growth, with active research taking place on growth in solution, especially in biomineralization processes. Established understanding of the growth of thin films and nanostructures is based around processes involving individual atoms or molecules. According to the author’s research over the last two decades, however, the generation of charged gas phase nuclei is shown to be the rule rather than the exception in the CVD process, and charged gas phase nuclei are actively involved in the growth of films or nanostructures. This new understanding is called the theory of charged nanoparticles (TCN). This book describes how the non-classical crystallization mechanism can be applied to the growth of thin films and nanostructures in gas phase synthesis. Based on the author’s graduate lecture course, the book is aimed at senior undergraduate and graduate students and researchers in the field of thin film and nanostructure growth or crystal growth. It is hoped that a new understanding of the growth processes of thin films and nanostructures will reduce trial-and-error in research and in industrial fabrication processes.

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 Diamond Thin Films An Emerging Technology Past Present and Future written by Ashok Kumar Dua and published by Trans Tech Publications Ltd. This book was released on 2004-08-08 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diamond, as well as being a precious gem, is a versatile material par excellence. No other material comes anywhere near to matching its properties, which are both extreme, and also expressed in rare combinations. However, natural diamonds, and those synthesised under high sandpressure temperatures, are too expensive or small for many technological applications. These limitations can be overcome by using large-area diamond coatings; chemically bonded to inexpensive non-diamond surfaces. The consequent economic advantages provide the driving force for much diamond-related research and technology.

Book excerpt: It is now over thirty years since a method was first described for the pyrolysis of hydrocarbons to form thin film diamond. We are now entering a new phase, in which potential applications of this unique material are driving improved understanding of diamond synthesis, better control of both phase purity and structural perfection, and engineering advances that will reduce the cost and increase the deposition rate. In this highly competitive area, researchers from many countries have contributed to our knowledge base, and there are several established international conferences concentrating on diamond thin films. This book brings together some of the key components in what is an exciting scientific and technical challenge: to establish diamond as an engineering material that will revolutionise operations in optics, mechanics and electronics. The sequence of papers in the book moves from fundamental studies of the deposition process, the surface structure of diamond and its stability, and the nucleation of diamond on a foreign substrate, through the current capacity for achieving epitaxial quality films, to the characterisation of diamond quality. The final section describes some of the variety of applications, and their requirements, that are being introduced to potential users.

Available in PDF, EPUB and Kindle. Book excerpt: We studied the chemical nature of the substrate and the role of buffer layers on nucleation and growth of diamond during chemical vapor deposition (hot-filament). The transition metals with partially filled d-atomic orbitals are found to stabilize SP2 bonding which leads to enhanced precipitation of SP2 bonded non-diamond carbon phases such as graphite, amorphous and glassy carbon films. We have shown that by alloying these metals with electron donating elements, it is possible to stabilize SP3 bonding and form diamond film directly on the metallic substrates. Similar studies on nucleation and growth of diamond have been performed using AlN buffer layers. The results from these studies are compared with those obtained using buffer layers. By using these concepts, we have minimized the formation of graphitic layers and improved the adhesion of diamond layers on non-carbide forming metallic substrates.

Available in PDF, EPUB and Kindle. Book excerpt: In the area of nucleation, it was discovered that C--0 thin films are perfect substitutes for diamond seeds in the growth of diamond films. This research, along with a careful study of diamond growth on carbon ion implanted single crystal copper, have clearly demonstrated that structured carbon is the best precursor for nucleation and growth of diamond films on non-diamond surfaces. In addition, by using fluorine chemistry during diamond growth, it has been shown that diamond films can grow on carbide substrates without the pretreatment of diamond seeding. The growth rates are higher and the film adhesion is much improved.

Available in PDF, EPUB and Kindle. Book excerpt: Chemical vapor deposition (CVD) has been the main method for synthesizing diamond thin films on hetero substrate materials since 1980s. It has been well acknowledged that both nucleation and growth of diamond on non-diamond surfaces without pre-treatment are very difficult and slow. Furthermore, the weak adhesion between the diamond thin films and substrates has been a major problem for widespread application of diamond thin films. Up to now, Si has been the most frequently used substrate for the study of diamond thin films and various methods, including bias and diamond powder scratching, have been applied to enhance diamond nucleation density. In the present study, nucleation and growth of diamond thin films on Ti3SiC2, a newly developed ceramic-metallic material, using Microwave Plasma Enhanced (MPE) and Hot-Filament (HF) CVD reactors were carried out. In addition, synchrotron-based Near Edge Extended X-Ray Absorption Fine Structure Spectroscopy (NEXAFS) was used to identify the electronic and chemical structures of various NCD films. The results from MPECVD showed that a much higher diamond nucleation density and a much higher film growth rate can be obtained on Ti3SiC2 compared with on Si. Consequently, nanocrystalline diamond (NCD) thin films were feasibly synthesized on Ti3SiC2 under the typical conditions for microcrystalline diamond film synthesis. Furthermore, the diamond films on Ti3SiC2 exhibited better adhesion than on Si. The early stage growth of diamond thin films on Ti3SiC2 by HFCVD indicated that a nanowhisker-like diamond-graphite composite layer, different from diamond nucleation on Si, initially formed on the surface of Ti3SiC2, which resulted in high diamond nucleation density. These results indicate that Ti3SiC2 has great potentials to be used both as substrates and interlayers on metals for diamond thin film deposition and application. This research may greatly expand the tribological application of both Ti3SiC2 and diamond thin films. The re.

This book was released on 2006-03-30 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are pleased to present the Proceedings of the NATO Advanced Research Workshop “Syntheses, Properties and Applications of Ultrananocrystalline Diamond” which was held June 7-10, 2004 in St. Petersburg, Russia. The main goal of the Workshop was to provide a forum for the intensive exchange of opinions between scientists from Russia and NATO countries in order to give additional impetus to the development of the science and applications of a new carbon nanostructure, called ultrananocrystalline diamond (UNCD) composed of 2-5 nm crystallites. There are two forms of UNCD, dispersed particles and films. The two communities of researchers working on these two forms of UNCD have hitherto lacked a common forum in which to explore areas of scientific and technological overlap. As a consequence, the two fields have up to now developed independently of each other. The time had clearly come to remedy this situation in order to be able to take full advantage of the enormous potential for societal benefits to be derived from exploiting the synergistic relationships between UNCD dispersed particulates and UNCD films. The NATO sponsored ARW therefore occurred in a very timely manner and was successful in beginning the desired dialogue, a precondition for making progress toward the above stated goal. The discovery of UNCD completes a triadof nanostructured carbonswhich includes fullerenes and nanotubes.
