载能团簇离子的非线性辐照损伤

由于团簇离子在能量损失、二次离子发射和辐照损伤上的非线性效应，所以团簇离子与物质的相互作用倍受关注。对团簇作用的非线性效应研究不仅对于了解团簇离子与物质相互作用的机制具有十分重要的理论意义，而且载能团簇离子还有可能成为材料表面改性与分析、新功能材料的合成与研究的一种有效的新手段。因此，团簇离子与物质的相互作用成为当今国际上的研究热点之一。主要评述了载能团簇离子在物质中的非线性辐照损伤，介绍了典型的研究方法和实验结果。 Due to energetic cluster produces simultaneous impacts of several atoms and deposits extremely high energy density in a very small area, the cluster impingement on solids has produced non-linear radiation damages not presented in the collisions of individual atoms with those solids. The radiation damages are usually investigated by channeling Rutherford backscattering, Scanning Tunneling Microscope （STM）, Transmission Electronic c Microscope（TEM） and computer simulation. The typical methods and results on the non-linear radiation damages induced by clusters are reviewed in this paper.
