利用分子动力学模拟系统研究了低能Pt38,Pt1 41 和Pt2 6 6 原子团簇与Pt(0 0 1)表面的相互作用过程 ,详细分析了初始原子平均动能为 0 .1,1.0和 10eV的原子团簇的沉积演化过程及其对基体表面形貌的影响 .研究表明 ,初始原子平均动能是描述低能原子团簇的重要参量 .当团簇的平均原子动能较低时 ,团簇对基体表层原子点阵损伤较小 ,基本属于沉积团簇 ;随着入射团簇的原子平均动能的增加 ,团簇对表层原子点阵结构的破坏能力增强 ,当团簇的原子平均动能增加到 10eV时 ,团簇已经显现出注入特征 .低能原子团簇对基体表面形貌的影响主要取决于团簇的初始原子平均动能 ,但随着团簇所含原子数目的增加 ,低能原子团簇对基体表面的影响略有增强 .此外 ,对低能原子团簇与基体表面相互作用的物理机理进行了讨论 The interaction between low-energy Pt38, Pt1 41 and Pt2 6 6 clusters and Pt (001) surfaces was investigated by molecular dynamics simulations. The atomic clusters with initial kinetic energy of 0.1, 1.0 and 10 eV were analyzed in detail And the effect on the surface morphology of the substrate.The results show that the average kinetic energy of the initial atoms is an important parameter to describe the low-energy atomic clusters.When the average atomic kinetic energy of the clusters is low, the atomic cluster damage Smaller and basically belong to the sedimentary clusters. With the increase of the average atomic kinetic energy of the incident clusters, the ability of the clusters to destroy the atomic lattice structure of the surface layer is enhanced. When the average atomic kinetic energy of the clusters is increased to 10 eV, the clusters have appeared The effects of low-energy atomic clusters on the surface morphology of the matrix mainly depend on the average initial kinetic energy of the clusters, but the influence of low-energy atomic clusters on the surface of the matrix is ​​slightly enhanced as the number of atoms in the clusters increases , The physical mechanism of the interaction between low-energy atomic clusters and the substrate surface is discussed
