| 摘 要： | 利用分子动力学方法模拟了碳原子与碳氢薄膜的作用过程。探讨了不同入射能量对碳原子与碳氢薄膜相互作用的影响。模拟结果表明碳原子与碳氢薄膜作用会在表面形成碳薄膜。随着入射能量的增加，碳薄膜厚度变薄。在碳薄膜中碳原子的成键形式主要为Csp2-Csp2和Csp2-Csp3，随入射能量的增加，碳原子键价结合形式从Csp2-Csp2向Csp2-Csp3转化。

| Abstract: | 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. |
