| 摘 要： | 根据化学键理论和非晶态结构的短程有序,设计了晶态团簇NNiP2,Ni2P2,Ni 3P2,Ni4P2的四种构型,并用DFT方法对他们的几何结构型进行高水平的量子化学计算.结果表明,模型体系中P原子供给Ni原子电子这与非晶态合金Ni81.5,5p18.5的实验结构一致,说明NiP2,Ni2P2,Ni 3P2,Ni4P2原子簇模型能反映非晶态Nig1.5 P18.5的结构特点.

| Abstract: | According to chemical bond theory and short_range_ordering in the amorphous alloy,4 models for non_crystalline cluster NiP 2,Ni 2P 2,Ni 3P 2,Ni 4P 2 have been designed and their geometric models calculated by DFT method.The results showed that phosphor is a electrondonor in the Ni_P amorphous alloy,while nickel is a electron_acceptor,which agrees well with the experimental results for amorphous alloy Ni 81 5 P 18 5 .It could be concluded that the models of NiP 2,Ni 2P 2,Ni 3P 2,Ni 4P 2 clusters is able to reflect the sturcture features of Ni 81 5 P 18 5 amorphous alloy. |
