Abstract
Irradiation effecs, mainly including transformation from crystalline into amorphous state, of C, films induced by 120keV H, Ar and Fe ions irradiation were analysed by means of Raman scattering technique. The results indicate that amorphization process in the cases of Ar and Fe ions irradiation is dominated by nuclear collision, but in the case of H ion irradiation, the process is dominated by electronic energy transfer. The annealing effect of electronic energy loss which induced the intermediate graphitization process before amorphization in lower irradiation dose ranging from 2 X 10_14 ions/cm~2 to 5 X 10_16 ions /cm~2 was found in the case of H ion irradiation for the first bine.
