Synchrotron Radiation Photoemission

We report the electronic structure of the interface of the ultrafilm Fe film with the O -terminated ZnO (000-1) polar surface studied by synchrotron radiation photoemission. It was found that Fe grows in a Stranski–Krastanov mode. The turning point of the growth mode was at the Fe coverage of ~2 Å. At low coverage, about 1 ML (monolayer) of iron (ca. 1.5 Å) was oxidized by the terminative oxygen atoms on the ZnO (000-1) surface. Analysis of the valence band and the Fe 3 p photoemission spectra indicates that below 2 Å coverage, only Fe 2+ species could be detected at the Fe / ZnO interface, after that the formation of a metallic iron overlayer was observed. A sharp Fermi edge appeared at 5.1 Å coverage, indicating the formation of the bulk metallic Fe film. Furthermore, work function of the sample decreased to a minimum of 4.5 eV at 0.2 Å Fe , and then to 4.9 eV with the formation of a dipole layer at the interface.
