Understanding adsorption geometry of organometallic molecules on graphite.

ABSTRACT: To comprehensively investigate the adsorption geometries of organometallic molecules on graphene, Cp^*Ru⁺ fragments as an organometallic molecule is bound on highly oriented pyrolytic graphite and imaged at atomic resolution using scanning tunneling microscopy (STM) (Cp^* = pentamethylcyclopentadienyl). Atomic resolution imaging through STM shows that the Cp^*Ru⁺ fragments are localized above the hollow position of the hexagonal structure, and that the first graphene layer adsorbed with the fragments on the graphite redeveloped morphologically to minimize its geometric energy. For a better understanding of the adsorption site and molecular geometry, experimental results are compared with computed calculations for the graphene surface with
