| 摘 要： | 磺化酞菁铜多层膜体系是利用Langmuir-Blodgett技术制备的有序有机分子膜,它对于XPS测试有很好的稳定性,本文在固定电子出射角的条件下利用XPS方法研究了不同厚度的膜样品中Cu_((2(?))_(3/2))、Ni_(1(?))、S_(2p)峰强度的变化规律,讨论了膜内分子有序排列引起的散射效应对电子平均自由程的影响。

| Abstract: | Multilayer system of copper phthalocyanine-tetrasulphonate is an ordered organic molecular film assembled by LB technique. It is very stable for XPS measurement. In this work, we studied the peak intensity variation of Cu2 3*2 NI,, Si, in the samples with different thicknesses of the film at a-constant take-off-angle and obtained the inelastic mean free path 26, 22, 48 A respectively. We also gave explanation to the influence of scattering effect caused by the ordered molecular orientation on the inelastic mean free path. |
