Communication: Influence of graphene interlayers on the interaction between cobalt phthalocyanine and Ni(111)

J Chem Phys. 2013 Feb 28;138(8):081101. doi: 10.1063/1.4793523.

Abstract

The influence of graphene interlayers on electronic interface properties of cobalt phthalocyanine on Ni(111) is studied using both photoemission and X-ray absorption spectroscopy. A charge transfer associated with a redistribution of the d-electrons at the Co-atom of the phthalocyanine occurs at the interface to Ni(111). Even a graphene buffer layer cannot prevent the charge transfer at the interface to Ni(111); however, the detailed electronic situation is different.
