We present a new outlook at the study of metal-semiconductor interface formation. A resonant photoemission spectroscopy tuned to the Fe 3p-3d transition (56 eV) was used to investigate the changes after sequential deposition of Fe atoms on freshly cleaved Cd_{0.86}Fe_{0.14}Se crystal surface. In the first stages (0.6-4 ML) of Fe deposition the contribution of Fe 3d electrons to the valence band grows up markedly indicating the increase in Fe content in the Cd_{0.86}Fe_{0.14}Se crystal surface region. When the amount of Fe exceed 40 ML the resonant photoemission spectra became similar to the Fe metal with some contribution of the ternary crystal substrate.

Photoemission measurements using synchrotron radiation were performed on PbYbTe (bulk crystal) and CdYbTe (MBE thin film). The resonant enhancement of the photoemission was applied for investigation of the contribution of Yb 4f electrons to the valence band. The set of the energy distribution curves was collected for energies in the region close to the 4d-4f Fano transition. The Yb 4f^{14} were observed at the binding energies close to the edge of the valence band while the 4f^{13} states were revealed deep in the valence band.
