In-situ LEEM investigation of the growth of organic monolayers on metal surfaces — •Janina Felter, Caroline Henneke, Jana Wolters, and Christian Kumpf — Peter Grünberg Institut (PGI-3), Forschungszentrum Jülich, 52425 Jülich, Germany, and Jülich Aachen Research Alliance (JARA)-Fundamentals of Future Information Technology, Germany

The adsorption of organic molecules on metal surfaces are of highest relevance for applications in the field of organic electronics and for fundamental studies of the interaction mechanisms. In particular, a deep understanding of the nucleation and the formation of the first molecular layer is necessary since this layer acts as a template for further growth and determines the electronic properties of the interface. By using LEEM, PEEM and µLEED, we studied the growth dynamics of Copper-II-phthalocyanine (CuPc) and 1,4,5,8-naphthalene-tetracarboxylic-acid dianhydride (NTCDA) monolayers on low-indexed metal surfaces in-situ and in real-time. Besides others, we have observed the transformation of CuPc domains into each other during and after deposition on Ag(111). In an ongoing PEEM-based ARPES study, we also investigate the electronic properties of these metal-organic interfaces.
