Copper Phthalocyanine Monolayers and Multilayers on Ag(110) and Ag(111) surfaces — •Kathrin Schönauer1,2, Martin Willenbockel1,2, Benjamin Stadtmüller1,2, Christian Kumpf1,2, Sergey Soubatch1,2, and Stefan Tautz1,2 — 1Peter Grünberg Institut (PGI-3), Forschungszentrum Jülich, 52425 Jülich, Germany — 2JARA - Fundamentals of Future Information Technology, Germany
Organic semiconductors and their potential for applications in electronic devices such as solar cells and organic light emitting diodes make them interesting for fundamental research. Especially interfaces between different organic layers, e.g. PTCDA and CuPc, are subjects of experiments. To create a basis for the understanding of heteroorganic systems, the corresponding homomolecular phases are investigated regarding their geometric and electronic structure upon adsorption on a metal surface. While homomolecular phases of PTCDA on different noble metal surfaces are well-studied, less is known about adsorption and ordering of CuPc. Here we present a combined study employing (SPA)LEED, STM, STS and ARUPS to CuPc monolayers and multilayers adsorbed on the Ag(110) and Ag(111) surfaces.
