Der Schwerpunkt der Experimente lag in der Bestimmung der lateralen geometrischen Strukturen mit hochauflösender Elektronenbeugung (SPA-LEED) und Rastertunnelmikroskopie (STM), sowie der Adsorptionshöhen mit der Methode der stehenden Röntgenwellenfeldern (NIXSW). Hochauflösende Elektronenenergieverlustspektroskopie (HREELS) wurde verwendet, um die vibronische Struktur und den dynamischen Ladungstransfer an der Grenzfläche zu charakterisieren. Die elektronische Struktur und der Ladungstransfer in die Moleküle wurde mit ultraviolett Photoelektronenspektroskopie (UPS) gemessen. Die wichtigsten Ergebnisse dieser Arbeit betreffen den Zusammenhang zwischen Adsorbat-Substrat Wechselwirkung und der Adsorbat-Adsorbat Wechselwirkung von Phthalocyaninen im Submonolagenbereich.show moreshow less
  • In this thesis the adsorbate systems CuPc/Ag(111), CuPc/Au(111), CuPc/Cu(111), H2Pc and TiOPc/Ag(111) were investigated and characterized in great detail using complementary methods. The focus of the experiments was the determination of lateral geometric structures with spot-profile-analysis low energy electron diffraction (SPA-LEED) and scanning tunneling microscopy (STM), as well as the measurement of adsorption heights using the method of normal incidence x-ray standing waves (NIXSW). High resolution electron energy loss spectroscopyIn this thesis the adsorbate systems CuPc/Ag(111), CuPc/Au(111), CuPc/Cu(111), H2Pc and TiOPc/Ag(111) were investigated and characterized in great detail using complementary methods. The focus of the experiments was the determination of lateral geometric structures with spot-profile-analysis low energy electron diffraction (SPA-LEED) and scanning tunneling microscopy (STM), as well as the measurement of adsorption heights using the method of normal incidence x-ray standing waves (NIXSW). High resolution electron energy loss spectroscopy (HREELS) was used to characterize the vibronic properties of the molecule and the interface dynamical charge transfer (IDCT). The electronic structure and the charge transfer into the molecule were investigated with ultraviolet photoelectron spectroscopy (UPS). The most important results of this work are related with the interplay between adsorbate-substrate and adsorbate-adsorbate interaction of Phthalocyanines in the submonolayer regime.show moreshow less
