Investigation of the influence of graphene interlayers on the interaction between cobalt phthalocyanine and Ni(111) by X-ray photoemission and absorption spectroscopies — •Johannes Uihlein¹, Heiko Peisert¹, Mathias Glaser¹, Małgorzata Polek¹, Hilmar Adler¹, Fotini Petraki¹, Ruslan Ovsyannikov², Maximilian Bauer², and Thomas Chassé¹ — ¹Institut für Physikalische und Theoretische Chemie, Auf der Morgenstelle 18, 72076 Tübingen, Germany. — ²Helmholtz Zentrum Berlin für Materialien und Energie GmbH, Elektronenspeicherring BESSY II, Albert-Einstein-Str. 15, 12489 Berlin, Germany.

The interactions appearing at interfaces between transition metal phthalocyanines (TMPCs) and metal substrates play an important role for electron transportation processes in optoelectronic devices and spintronic nanodevices. These molecule-substrate interactions also can drastically influence the magnetic properties of the adsorbed molecules. However, these interactions might be tuned by the insertion of an interfacial buffer layer in between the metal substrate and the adsorbed molecules. With its outstanding electronic properties, graphene promises to be an excellent candidate for the tuning of interface properties. Its influence on the interactions between cobalt phthalocyanine and a Ni(111) single crystal surface has been investigated by X-ray photoemission and absorption spectroscopies.
