The valence-band and conduction-band electronic structure of pyrite-type CoSe 2 has been investigated by means of ultraviolet-photoemission, synchrotron-radiation-photoemission and inverse-photoemission spectroscopies. The fully occupied Co 3d states with t 2g symmetry are observed as a main peak at -1.0 eV relative to the Fermi level (E F ), and the partially filled Co 3d states with e g symmetry are observed as a shoulder at the E F side of the main peak. On the other hand, the structure due to the unoccupied Co e g states appears at 0.6 eV in the inverse-photoemission spectrum. The electronic structure of CoSe 2 is similar to that of CoS 2. The electron correlation is more important for CoSe 2 than for CoS 2.

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.
