Molecular Picture

The photoelectron spectroscopy of size-selected [Formula: see text](n=3–24) clusters and oxygen-chemisorbed clusters Fe n O −(n=1–16), has been studied at 3.49-eV photon energy with a magnetic-bottle time-of-flight photoelectron spectrometer. While the spectra of the pure iron clusters show rather sharp features in the whole size range, those of the oxygen-chemisorbed species are considerably different, with extensive sharp structures observed for n only up to 6. The electron affinities (EAs) of both the bare and chemisorbed clusters exhibit strong size variations. However, the first oxygenation of the iron clusters induces a systematic lowering of EA in the size range n=9–15. Towards a complete molecular picture of these interesting clusters, density-functional calculations are being performed to determine the equilibrium cluster structures, oxygen chemisorption sites, and their electronic structures. The equilibrium structures obtained for Fe n O with n=2–6 are reported.

ABSTRACTLocal electronic structures of C60-Co hybrid films have been studied by X-ray photoelectron spectroscopy (XPS) and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy. XPS spectra of C 1s main and satellite peaks for the C60-Co films show binding-energy shifts and also line-broadening compared to those in a pure C60 film. In addition, XPS spectra in valence band region suggest an appearance of three new components at near Fermi level and HOMO level in the C60-Co film. These results are attributed to hybridizations between Co 3d band and C60 LUMO. The same effects have been observed in NEAXFS spectra at C 1s excitations.
