Opis:: The electronic band structure of Mn/ZnTe(110) (1×1) has been studied by angle-resolved photoelectron spectroscopy. The sets of spectra were acquired for the clean surface and after in situ deposition of 0.4 ML of Mn, in order to compare the band structures and to reveal changes brought about by the presence of Mn. The experimental band structure diagram of Mn/ZnTe along theΓ-K direction in the Brillouin zone has been derived from the experimental data. Indications of interaction between the Mn 3d states and sp$\text{}^{3}$ bands of the semiconductor are discussed.

Opis:: Resonant photoemission spectroscopy, with application of synchrotron radiation, was used to study the valence band electronic structure of clean surface of (EuGd)Te layers. Fano-type resonant photoemission spectra corresponding to the Eu 4d-4f transition were measured to determine the contribution of 4f electrons of Eu$\text{}^{2+}$ and Eu$\text{}^{3+}$ ions to the valence band. The resonant and antiresonant photon energies of Eu$\text{}^{2+}$ ions were found as equal to 141 V and 132 eV, respectively and for Eu$\text{}^{3+}$ ions were found as equal to 146 eV and 132 eV, respectively. Contribution of Eu$\text{}^{2+}$4f electrons was found at the valence band edge while for Eu$\text{}^{3+}$ it was located in the region between 3.5 eV and 8.5 eV below the valence band edge.
