The epitaxial growth of beta-Sic nanocrystals at the Si{sup 16}O{sub 2}/Si(100) interface under CO annealing has been studied using {sup 13}C{sup 18}O and isotopically sensitive nuclear reaction analysis and secondary ion mass spectrometry analysis. The results show that the amount of SiC increases linearly with the CO pressure and the annealing time. We demonstrate that the CO diffuses as a molecule in the silica and that for each C atom reacting to form SiC, an oxygen atom is incorporated in the vicinity of the interface. The linear and the parabolic rate constants corresponding to an adapted Deal and Grove model are also determined.
