| 摘 要： | 本文研究了氧族元素S和Se在Ni(001)衬底上形成的P(2×2)和C(2×2)两种结构吸附系统依赖于能量的光电子衍射曲线的直接Fourier变换分析方法,考虑了在不同能量范围内作Fourier变换对峰值位置的影响,求得了这些系统的各级层距修正值Δα,讨论了利用这些Δα值和实验EDPDFT数据来决定表面结构的可能性。

| Abstract: | Direct Fourier-transform analysis method for energy-dependent photoelectron-dif-fraction curves of Se-Ni(001) and S-Ni(001) systems has been studied. The effect of different energy range in which Fourier-transformation was performed on △a (layer-spacing modification) was considered. The possibility that surface structure could be determined by using these △a value and FT of experimental EDPD data has been discussed. |
