Abstract

Abstract: Multilayer system of copper phthalocyanine-tetrasulphonate is an ordered organic molecular film assembled by LBtechnique. It is very stable for XPSmeasurement. In this work, we studied the peak intensity variation of Cu_{2P_3/2}、Ni_1v、S_2p in the samples with different thicknesses of the film at a-constant take-off-angle and obtained the inelastic mean free path 26, 22, 48Å respectively. We also gave explanation to the influence of scattering effect caused by the ordered molecular orientation on the inelastic mean free path.

Key words: X-ray photoelectron spectroscopy, Multilayer system, Electron inelastic mean free path
