Recent photoemission spectroscopy results have shown a charge transfer between thin films of manganese and cobalt phthalocyanine molecules. The charge transfer at the interface of these molecules could significantly influence electronic transport properties of the system. Therefore, the main goal of the present project is the investigation and the understanding of the interplay between the charge transfer and electrical conductance at the interfaces of manganese and cobalt phthalocyanines. For this purpose, several structures containing thin films and/or single crystals of these molecules will be prepared and studied. Moreover, interactions between phthalocyanine molecules and well-known charge transfer organic single crystal semiconductors (TCNQ, TTF) will be investigated. Here, one can expect charge transfer effects leading to changes in the conductance at the interface of the two materials.

最近的光电子能谱结果表明，锰和钴酞菁分子的薄膜之间的电荷转移。这些分子界面的电荷转移对体系的电子输运性质有重要影响。因此，本项目的主要目标是研究和理解锰和钴酞菁的界面电荷转移和电导之间的相互作用。为此，将制备和研究含有这些分子的薄膜和/或单晶的几种结构。 此外，酞菁分子和著名的电荷转移有机单晶半导体（TCNQ，TTF）之间的相互作用将进行研究。在这里，可以预期电荷转移效应会导致两种材料界面处电导的变化。
