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.

- 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.

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.
