用X射线光电子能谱和吸收光谱相结合的方法研究了生长在铜(119)面上并五苯层的吸附。芳环上离域的pi分子轨道与下层铜衬底之间的显著相互作用被界面上的C1s核心能级多重峰所驱逐。并五苯分子几乎平躺在铜平台上的吸附几何形状被Cis的极化依赖性吸收特征所证实。(C)2007 Elsevier B.V.保留所有权利。
A combined X-ray photoemission and absorption spectroscopy study of the adsorption of pentacene layers grown on the Cu(119) vicinal surface is presented. A significant interaction between the pi molecular orbitals delocalized on the aromatic rings and the underlying copper substrate is evicted by C 1s core levels manifold peaks at the interface. Adsorption geometry with pentacene molecules almost flat-lying along the Cu terraces is confirmed by the polarization dependence of the C Is absorption features. (C) 2007 Elsevier B.V.
