Status and Applications of Diamond and Diamond-Like Materials: An Emerging Technology
Abstract
Recent discoveries that make possible the growth of crystalline diamond by chemical vapor deposition offer the potential for a wide variety of new applications. This report takes a broad look at the state of the technology following from these discoveries in relation to other allied materials, such as high-pressure diamond and cubic boron nitride. Most of the potential defense, space, and commercial applications are related to diamond's hardness, but some utilize other aspects such as optical or electronic properties. The growth processes are reviewed, and techniques for characterizing the resulting materials' properties are discussed. Crystalline diamond is emphasized, but other diamond-like materials (silicon carbide, amorphous carbon containing hydrogen) are also examined. Scientific, technical, and economic problem areas that could impede the rapid exploitation of these materials are identified. Recommendations are presented covering broad areas of research and development. Keywords: Diamond, Diamond-like hydrocarbons/carbons, Chemical & vapor deposition processes, Ion implantation, Characterization techniques, Thermal conductivity, Applications, R&D issues, Mineralogy.
