Investigation of electronic and structural properties of cobalt phthalocyanine on graphene interlayers on Ni(111) — •Hilmar Adler, Johannes Uihlein, Heiko Peisert, Małgorzata Polek, Fotini Petraki, and Thomas Chassé — Institut für Physikalische und Theoretische Chemie, Auf der Morgenstelle 18, 72076 Tübingen, Germany

Transition metal phthalocyanines (TMPcs) gained increasing attention due to their tunable properties, and therefore their application in light-emitting diodes, field-effect transistors and solar cells. Most recently, the interface between TMPcs and metal substrates raised additional interest due their important role in spintronic nanodevices. Depending on the substrate TMPcs may show strong interactions at the interface.[1] The molecule-substrate interaction at the interface can be further tuned by insertion of a buffer layer. Graphene with its exciting electronic properties is an ideal candidate for such layers. Cobalt phthalocyanine as a representative of TMPcs was investigated on Ni(111) with a graphene buffer layer by scanning tunneling microscopy. The results are compared to X-ray photoelectron spectroscopy measurements and X-ray absorption spectroscopy studies.
