- •
Growth of FeO layers on Pt(111) is found to consecutively reduce the work function of the system.
- •
The electrostatic compression effect and the structural relaxation make major contributions to the reductions.
- •
Significant rectifying effect observed in the FeO layer is induced by band alignment shift as work function changing.
