abstract = {Atomic force microscopy (AFM) and Fano-type resonant
photoemission spectroscopy (RPS) of Gd atoms deposited on
Si(1 1 1) surface are presented. Layers of thicknesses 0.2,
2 and 15 nm were deposited under UHV conditions. Anomalously
deep craters were observed on the Si(1 1 1) surface side of
the interface below the Gd layer. We expect that anomalously
high chemical activity of Gd and a dominating diffusion of
Si atoms are responsible for the effect. Application of
synchrotron radiation in the energy region hν corresponding
to the Gd 4d–4f transition (140–170 eV) enabled
Fano-type resonant photoemission spectra. Si(1 1 1) surface
valence band spectra with contributions from Gd 4f electrons
were detected for a 0.2-nm-thick Gd layer deposited onto a
clean Si(1 1 1) surface. The photoemission study revealed a
Fano resonance shape of the curve with resonance and
antiresonance energies hv=151.8 and 146.8 eV, respectively.
The Gd 4f localized electrons contribute to the valence band
density of states located at 9.8 eV below the valence band
edge.},
