Book Description
Boron-doped single crystal diamond films were grown homoepitaxially on synthetic (100) Type Ib diamond substrates using microwave plasma assisted chemical vapor deposition. A modification in surface morphology of the film with increasing boron concentration in the plasma has been observed using atomic force microscopy. Use of nitrogen during boron doping has been found to improve the surface morphology and the growth rate of films but it lowers the electrical conductivity of the film. The Raman spectra indicated a zone center optical phonon mode along with a few additional bands at the lower wavenumber regions. The change in the peak profile of the zone center optical phonon mode and its downshift were observed with the increasing boron content in the film. Furthermore, sharpening and upshift of Raman line was observed in the film that was grown in presence of nitrogen along with diborane in process gas.

Book Description
Diamond is the record-setter in many mineralogical properties such as hardness, diffusivity, thermal conductivity, purity, and covalency of bonding. Similarly, diamond, as the premier gemstone of the mantle holds primacy for geological features such as age and depth of origin. Diamond was among the first crystalline structures to be solved by X-ray diffraction and the first materials measured for their Raman spectrum. At more than 80 billion USD in yearly commercial value, diamond sets the record for the most traded, valuable mineral on the planet. Despite its chemical simplicity, diamond has been the object of more research effort, and had more scientific and popular press pages written about it, than any other mineral.

Book Description
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.
