Abstract: The primary focus of this study was to analyze molecule-substrate and molecule-molecule interactions in heteromolecular monolayers on metallic substrates using a number of high precision experimental techniques capable of measuring the electronic and geometric properties of surfaces and ultrathin films. Therefore the first part of this works compares the geometric and electronic properties of two prototypical heteromolecular monolayer systems: CuPc+PTCDA/Ag(111) and SnPc+PTCDA/Ag(111). For one of these experimental techniques, the XSW technique, several issues were recognized that were caused by effects so far not recognized in the literature. As such, the second part of this thesis describes improved ways of analyzing NIXSW data, considering non-dipolar effects and the attenuation of the measured signal by inelastic scattering. To elaborate, in the first section, we present a systematic study of the geometric and electronic properties of hetero-organic monolayers consisting of SnPc and PTCDA adsorbed on the Ag(111) surface and we compare these properties with those of monolayers containing CuPc and PTCDA. The geometric structures of these layers has been studied with LEED, STM and the NIXSW technique, while their electronic structure has been analyzed using ARPES data that has been analyzed using the photoemission tomography technique.
