Book excerpt: The studies covered in this dissertation concentrate on the various forms of diamond films synthesized by chemical vapor deposition (CVD) method, including microwave CVD and hot filament CVD. According to crystallinity and grain size, a variety of diamond forms primarily including microcrystalline (most commonly referred to as polycrystalline) and nanocrystalline diamond films, diamond-like carbon (DLC) films were successfully synthesized. The as-grown diamond films were optimized by changing deposition pressure, volume of reactant gas hydrogen (H2) and carrier gas argon (Ar) in order to get high-quality diamond films with a smooth surface, low roughness, preferred growth orientation and high sp3 bond contents, etc. The characterization of diamond films was carried out by metrological and analytical techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD), atomic force microscopy (AFM) and Raman spectroscopy. The results of characterization served as feedback to optimize experimental parameters, so as to improve the quality of diamond films. A good understanding of the diamond film properties such as mechanical, electrical, optical and biological properties, which are determined by the qualities of diamond films, is necessary for the selection of diamond films for different applications. The nanocrystalline diamond nanowires grown by a combination of vapor-liquid-solid (VLS) method and CVD method in two stages, and the graphene grown on silicon substrate with nickel catalytic thin film by single CVD method were also investigated in a touch-on level.

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.

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.

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 1997 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diamond's unique properties are potentially superior among the existing substrate materials for electronic applications. Among these properties, diamond's physical hardness, molar density, thermal conductivity, and sound velocity are the highest while its thermal expansion coefficient, compressibility, and bulk modules are the lowest. Because of this unique combination of properties, diamond has diverse applications in electronics, optics, and material coatings. Scientists around the world have been studying possible applications of diamond and its synthesis by chemical vapor deposition (CVD) in the semiconductor industry for almost the latter half of this century. The use of bulk crystals severely limits semiconductor applications of diamond due to difficulty in doping, device integration, high cost, and small area of bulk diamond. Therefore, a great deal of effort has been undertaken by researchers around the world on diamond synthesis by chemical vapor deposition (CVD). With some of the same limitations, homoepitaxial growth of diamond is not considered to be a feasible solution. As a result, heteroepitaxial growth of diamond is being considered to be an attractive possibility. Heteroepitaxial diamond growth has been the main subject of research since the first successful growth of diamond thin films on foreign substrates was reported. Polycrystalline and highly oriented diamond thin films grown on various substrates, especially silicon, have been reported over the years. There also have been reports of device fabrication on diamond such as diamond based point contact transistors, Schottky diodes, and field effect transistors at a laboratory level. The technology has been very challenging and there remain many obstacles to overcome before diamond based devices are to become part of the semiconductor industry. For example, epitaxial growth of CVD diamond, selective doping, n-type doping, and metallization of the grown films are not totally understood due to the polycrystalline nature of CVD diamond films. The objective of this work is the study of hot-filament chemical vapor deposited boron doped polycrystalline diamond thin films grown on both silicon and sapphire. A new horizontal gas flow configuration rather than the typical vertical gas flow configuration is utilized to provide larger area and better quality films grown on these substrates. The study includes characterization of grown films using scanning electron microscopy, Raman spectroscopy, X-ray diffraction analysis, and electrical characterization. Two types of contacts to the films grown on silicon substrates are fabricated enabling various electrical measurements. However, on sapphire substrates, low volume resistivity diamond films are grown despite severe adhesion problems. The effects of various substrate pre-treatments, growth conditions, and doping concentrations are presented.
