Optische Eigenschaften ultradünner PTCDA & TiOPc Einzel- und Heteroschichten
… Methoden der Molekularstrahlepitaxie (OMBE), der differentiellen Reflexionsspektroskopie (DRS) und Photolumineszenzmessungen möglich. Dabei steht der Übergang vom Einzelmolekül zum molekularen Festkörper im Mittelpunkt. Der realisierte optische Aufbau ermöglicht es, die optischen Eigenschaften von …

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
We have measured the optical properties of films of the organic semiconductors PTCDA (3,4:9,10-perylene-tetracarboxylic dianhydride) and HBC (peri-hexabenzocoronene), prepared by Organic Molecular Beam Expitaxy (OMBE), on different substrates by means of Differential Reflectance Spectroscopy (DRS). …
