| 摘 要： | 本文用只考虑最近邻相互作用的紧束缚模型研究了卤素吸附原子在Ni(100)面上的相互作用能。利用相互作用能随吸附原子相对位置的变化,解释了吸附的二维层结构。讨论杂质的影响,发现杂质的存在有时可以改变吸附层结构。另外发现:相互作用能随耦合强度的减小呈振荡衰减趋势。

| Abstract: | The indirect interaction between two haloid adatoms are studied by using Tight-Binding model. Using the relation between the indir(?)ct interaction energies and the relative positions of the adatoms,we explain the structure of haloid monolayer chemisobed on Ni (100) . In addition, it is found that the introduction of impurity atom can exchange the structure and that the interaction energies have a damped oscillation behaviour with the decrease of the coupling strength between the adatoms and the host atoms. |
