Thin layers of organic molecules have attracted a wide interest since the dawn of organic electronics because the performances of those devices critically depend on interface properties. The system of lead-phthalocyanine (PbPc) on graphite has been studied intensively with scanning tunneling microscopy (STM) [1], photoemission electron microscopy PEEM [2], and two photon photoemission spectroscopy (2PPE) [3]. It was found that the electronic properties of the interface are coverage dependent [2]. Thus, for a comprehensive understanding of the results the structure of the PbPc layer is of interest. Therefore, a quantitative analysis of LEED measurements was carried out under varying conditions like temperature and coverage graphite single crystals and will be compared to STM, PEEM, and 2PPE results.
