Download or read book Homoepitaxial Growth Rate Studies on Diamond 110 111 and 100 Surfaces in a Hot Filament Reactor written by and published by . This book was released on 1992 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growth rates of homoepitaxial (110), (111), and (100) diamond films were experimentally determined, for the first time, in a hot filament reactor using methane and carbon tetrachloride as the carbon source. Methane concentrations from 0.07% to 1.03% in H2 were studied at a subsum temperature of 970 'C. Growth ran were found to be crystal-face dependent with respect to methane concentration, being linear or first order for the (100) orientation, sublinear for (110), and sigmoidal for (111). The observed growth kinetics of (111) suggest the viability of an acetylene mechanism for (111), along with the methyl radical mechanism at methane concentrations above 0.73%. CC14 concentrations from 0.06% to 0.69% in H2 were also investigated at a substrate temperature of 970 C. Growth rate behavior was similar to that of methane for all three crystal faces. The temperature dependence of the growth rates was also crystal-orientation dependent. At subsum temperatures above 730 C, growth rates are thought to be mainly transport limited, yielding effective activation energies of 8+/-3, 18 + or - 2, and 12+ or - 4 kcal/mol for (100), (110), and (111) orientations, respectively. At substrate temperatures below 730 C, growth rates are thought to be surface reaction rate-limited, with an overall effective activation energy of 50 + or -19 kcal/mol for the three crystal-orientations studied.

Download or read book Growth Kinetics of 100 110 and 111 Homoepitaxial Diamond Films written by and published by . This book was released on 1992 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diamond film growth by chemical vapor deposition (CVD) has burgeoned rapidly during the past decade, accompanied by considerable progress in fundamental understanding. Particular progress has been made in understanding chemistry taking place in the gas phase above the substrate and in identification of the precuror(s) primarily responsible for growth, but the details of reactions taking place on the growing surface are as yet unknown. However, despite the commercial importance of high growth rates and the potential for gaining insight into the details of the growth mechanism, only a handful of studies of the growth kinetics of polycrystalline diamond films have been reported.
