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: 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 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.

This book was released on 2023-07-02 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores chemical methods for thin film deposition with diverse nanostructured morphology and their applications. Unlike top-down techniques, chemical methods offer low cost, simplicity, and growth of nanostructured surface architecture with ease of small to large-scale area deposition. The book primarily focuses on innovative twelve chemical methods for thin-film deposition on one platform. Since each method has its own advantages and disadvantages, it is crucial to select the specific method for specific material to be deposited depending upon what type of application is targeted. Due to inclusive of diverse chemical deposition methods, researcher will have knowledge about best choice of the deposition method to be adopted. Inclusive methods discussed in the book are chemical bath deposition, successive ionic layer adsorption and reaction, ion exchange, electroless deposition, electrodeposition, hydrothermal, spray pyrolysis, spin coating, dip coating, doctor blade, screen printing, and sol-gel. The selection of the correct procedure for material to be deposited in thin film form depends on its unique process parameters based on the kind of application and its requirement. The role of preparative factors necessary for thin film alters properties related to structure and surface morphology, electrical conductivity and optical band gap which have been extensively discussed along with the underlying science of film synthesis. The book provides a comprehensive overview of the field of chemical methods for thin film synthesis to applications. In addition to synthesis, the book covers characterization, instrumentation, and industrial application of thin films. As a result, concentrated techniques will be of great interest to university/college professors, students and new engineers as well as postdocs and scientists in the area.

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.
