摘要
用分子动力学模拟的方法和Tersoff多体势函数对低能入射的C60分子在再构的金刚石（100）表面沉积的过程进行模拟研究．在C60初始入射能量为30eV和60eV垂直于表面入射时，入射的C60分子没有从金刚石表面反弹出来，而是与金刚石表面相互吸引而导致C60分子沉积在金刚石的表面．C60分子在沉积的过程中有微弱的形变震荡现象．而入射C60的大部分能量（近70％左右）都转化为金刚石衬底的内能．
By using the molecular dynamics simulation technique with all analytic many-body potential function, the deposition process of low-energy C60 cluster on reconstructed diamond (100) surface has been studied. Results obtained in this study indicate that the C60 with collision energies of 30 eV or 60 eV will deposit on but not reflect from the substrate surface by the attractive interaction between C60 and diamond. The C60 is alternatively expanded and compressed during the whole process. The most part of the impact energy (about 70% )transforms to be the internal thermal motion of diamond substrate.
