abstract = {The performance of molecule based electronic devices can be
improved by use of transition metal oxides (TMO) as charge
injection buffer layers between electrodes and organic
semiconductors. It is known that the appropriate energy
level alignment at the molecule/TMO interface determines the
efficiency of the respective TMO. Herein, scanning tunneling
microscopy is employed to characterize the interface formed
by fullerenes (C60) deposited on a titanium oxide (TiO)
ultrathin film, which is created by oxidation of a
Pt3Ti(111) surface. Individual C60 are identified with
orbital resolution, and the interfacial and intermolecular
interactions are characterized in detail. Furthermore, the
energy level alignment at the C60/TiO ultrathin film
interface is deduced based on scanning tunneling
spectroscopy data. The results demonstrate that the C60/TiO
interface corresponds to a type-I heterojunction and, thus,
is useful to decouple C60 molecules from the metallic alloy
surface.},
