Carbonization dynamics of Si surfaces using a hydrocarbon gas molecular beam was investigated. In case of carbonizing atomically clean Si surfaces with C2H2, single crystalline 3C-SiC layers were obtained only In the narrow range of a substrate temperature near 780 °C. Control of surface reaction by a cap of very thin surface oxide layer and gradual increase of substrate temperature during carbonization were found to be effective in forming single crystalline 3C-SiC layers reproducibly.
