Opis:: The electronic structure of a new semimagnetic semiconductor (Cd,Co)Se is studied by UPS and calculated by a tight-binding version of the disordered-local-moment theory. The theory accounts for the chemical disorder and for electron interactions within the Co 3d$\text{}^{7}$ shells. Both theory and experiment show Co 3d states deep in the valence band and also at the band edge. The last state seem to be responsible for unique properties of the Co-based semimagnetic semiconductors.

Opis:: A resonant photoemission was used to study the ternary crystal formation, when small amount of Fe atoms was deposited (in one monolayer range of thickness) on the clean CdTe(100) surface. The constant initial state spectra taken near the Fe 3p-3d transition after Fe deposition and then again after heating process show the existence of two Fano-like resonance. The differences of the energy distribution curves taken for both resonance and antiresonance, respectively, allow us to distinguish two kind of Fe 3d contributions to the valence band: one derived from the metallic Fe islands on the surface and the second - derived from the Fe atoms built into the Cd$\text{}_{1-x}$Fe$\text{}_{x}$Te crystal.

Opis:: We report the results of a resonant photoemission study of Zn$\text{}_{1-x}$Co$\text{}_{x}$S. A Co 3d derived contribution to the valence band spectra was revealed as a 5 eV wide structure with two maxima: at the edge of the valence band and about 4 eV below the edge. The results were compared with the total DOS distribution resulting from tight binding-coherent potential approximation calculations.
