| 摘 要： | Molecular dynamical simulation is carried out to investigate the effects of the incident energy on a-C：H film growth from C and tt atomic flux. Our simulations show that the film growth at low incident energy （1 eV） is dominated by the adsorption of H and C atoms. At moderate incident energy （10 and 20eV）, the abstraction reaction of incident H atoms with H atoms adsorbed at the surface becomes important. At high incident energy （30 and 40eV）, the a-C：H film growth is a two-step process： one is the adsorption and the shallow implantation of C atoms, and the other is the deep implantation of H atoms.
