Structure formation at organic-inorganic interfaces — •Florian Szillat and Stefan G. Mayr — Leibniz-Institut fuer Oberflaechenmodifizierung, Translationszentrum fuer regenerative Medizin und Fakultaet fuer Physik und Geowissenschaften der Universitaet Leipzig, Permoserstrasse 15, 04318 Leipzig

Organic-inorganic interfaces have attracted significant scientific interest during the past decade - primarily due to their applications in the fields of organic semiconductors and biomaterials. Detailed experimental and theoretical understanding - in particular of the inorganic-organic interaction - is still lacking. To address these aspects we employ polycarbonate thin films on metal alloy substrates, while our focus lies on structure formation during organic film deposition. Our metal alloy surfaces are prepared on thermally oxidized silicon wafers by electron beam evaporation, while polybisphenol A polycarbonate thin films are deposited afterwards by thermal evaporation. Structure formation is characterized primarily with atomic force microscopy and interpreted within the concept of stochastic rate equations for film growth in the presence of interfaces [1]. Based on these concepts, conclusions on the interface interactions are drawn.
