The growth of diamond in forms ranging from nanocrystalline films to large single crystals by chemical vapor deposition (CVD) has become an established technology in the last 20 years. CVD diamond materials are distinct from natural diamonds and synthetic diamonds grown in high temperature, high pressure (HTHP) presses. In the CVD process, one can control the purity, doping, defect structure, and morphology with, in principle, no limitations on size. CVD diamond materials now offer the opportunities to exploit the extreme properties of diamond for scientific and technological applications. I will present an overview of ?the standard model? of CVD diamond growth and highlight many of the applications of diamond materials in optics, electronics, chemical sensing and synthesis, tribology, and thermal management.

Bio: Dr. Butler received his S.B degree from MIT (1966) in chemical physics and his Ph.D. from the University of Chicago (1972) where he continued as a National Institutes of Health postdoctoral fellow. His graduate work was on the covalent bonding of 5f electrons in single crystals of UF6 doped with NpF6 using Electron Paramagnetic Resonance and 19F Electron Nuclear Double Resonance, and his postdoctoral research used picosecond spectroscopy to study cis-trans isomerization in model compounds for the visual receptor, retinal.  He joined the Naval Research Laboratory in 1975 where he applied laser spectroscopy to the study of elementary reaction dynamics, photochemistry, and gas phase chemical kinetics relevant to atmospheric and combustion chemistries. Following a sabbatical year at the Institute of Molecular Science in Japan (1982-3), he used high resolution IR laser diode spectroscopy to the study of reactive transient molecules relevant to plasma processing and chemical vapor deposition (CVD). From 1983-86 he applied insitu laser diagnostics to the gaseous and surface processes in CVD of various materials.  Beginning in 1987, Dr. Butler focused on the understanding of the growth chemistry and mechanisms of the newly reported CVD of diamond. His current research interests lie primarily with understanding and exploiting the growth, characterization, properties, and applications of chemical vapor deposited (CVD) diamond materials.
