Abstract: The AM1 semi-empirical quantum mechanical method has been used to calculate the mechanisms for adsorbing and kernel-forming on diamond(111) hydrogenated surface by using acetylene as growth species. The heats of formation(ΔHf) of each step in kernel-forming reaction pathway are obtained. The results show that acetylene can greatly contribute to the kernel-forming of diamond and that acetylene is the primary one of diamond growth species.

Key words: Diamond thin film, Acetylene, Kernel-forming mechanism, Potential barrier(Ed.: Q, X)
