Electronic Coupling Effects and Charge Transfer between Organic Molecules and Metal Surfaces
We employ a variant of optical absorption spectroscopy, namely in situ differential reflectance spectroscopy (DRS), for an analysis of the structure-properties relations of thin epitaxial organic films. Clear correlations between the spectra and the differently intense coupling to the respective …

Optical Properties of Organic Semiconductors: from Submonolayers to Crystalline Films
… (OMBE), on different substrates by means of Differential Reflectance Spectroscopy (DRS). The optical setup enables us to directly follow the thickness dependent optical properties of the organic films, starting from submonolayer coverage up to thicker films on the order of 20 monolayers (ML) …

Spectroscopic studies of alkali and zinc core levels in alkali metals
… of the Zn 3d core. The data were obtained by differential reflectance spectroscopy using synchrotron radiation on alloys quench-condensed at liquid He temeratures. Various excitation profiles at threshold are observed for alkali core excitations in alkali-alkali alloys. These profiles change …

Optische Eigenschaften ultradünner PTCDA & TiOPc Einzel- und Heteroschichten
In der vorliegenden Arbeit werden die optischen Eigenschaften von dünnen PTCDA und TiOPc Schichten untersucht. Dies wurde mit der Kombination der Methoden der Molekularstrahlepitaxie (OMBE), der differentiellen Reflexionsspektroskopie (DRS) und Photolumineszenzmessungen möglich. Dabei steht der …
