Two different SnO2(101) bulk terminations have been prepared in order to demonstrate the impact of the oxide surface composition on the interface properties between SnO2(101) and an organic film. The change in work function causes a rigid shift of the molecular orbitals of the condensed organic film by 1 eV with respect to the valence band of SnO2. This change in the band alignment between an organic film and an oxide electrode material allows tuning of the barriers for charge transfer across this interface in molecular electronics applications.
