| 摘 要： | Molecular dynamics method was used to investigate the interactions of C continuously bombarding the hydrocarbon film surface. The Brenner potential was chosen. The simulation results show that the amorphous carbon-rich layer was formed on the hydrocarbon surface. The thickness of the carbon-rich layer decreases with increasing incident energy. In the formed layer, C atoms bond chiefly with Csp2-Csp2 and Csp2-Csp3. With increasing incident energy, the hybridization of C atoms converts from Csp2-Csp2 to Csp2-Csp3.
