dc.description.abstract | In this study, the effect of hydrogen on the structure and mechanical properties of carbon films produced by selective etching of monolithic SiC was examined. The process to produce carbon films from SiC (i.e., SiC-derived carbon, CDC) was carried out in a gas mixture of Cl-2 and H-2 at 1000 degrees C for 20 h. The Raman intensity ratio, I-D/I-G, where subscripts D and G refer to diamond and graphite, decreased as the hydrogen concentration in the gas mixture increased, indicating a decrease in the sp(2) carbon cluster. XRD analysis also showed that the fraction of graphitization decreased as the hydrogen concentration increased. The addition of hydrogen that prevented the formation of graphite (sp(2) bonding) also resulted in a reduction in the film thickness. The hardness and elastic modulus of the carbon films tended to decrease as the H-2 content increased owing to the contribution from the C-H bond and the nano-size pore. (C) 2009 Elsevier B.V.
