While along[0 0 1]direction,the Gd adatom diffuses by exchanging. 而在 [0 0 1]方向则通过交换机理扩散 .

The diffusion mechanisms of Gd adatom on Cu(110) surface are investigated by means of molecular dynamics. 为了分析Gd吸附原子在Cu( 110 )表面的扩散机理

First, we study the structures of Ag adatom clusters supported on the metal Ag(111) surface using genetic algorithm. 我们首先用该遗传算法研究了金属Ag(111)表面Ag吸附团簇的结构。

Then, we study systematically the lowest-energy structures of adatom clusters on a series of metal fcc(110) surfaces. 接着，我们又系统的研究了金属fcc(110)表面吸附团簇的最低能量结构。

We find that the diffusion energy barrier is related to the type of step that an adatom belongs to. 计算结果表明吸附原子的扩散势垒与其所在表面所属台阶类型有关；

Moreover, the C adatom can diffuse a long distance on the surface while the adsorbed C2 is more likely to be confined in a local region. 单个C原子能够在Si表面扩散较长的距离，而C2分子则比较容易被限制在局部区域。
