Opis:: The valence band structure E(k) for CdTe (111) Cd side surface 2 x 2 reconstructed was investigated along the Γ-L direction of the bulk Brillouin zone by high-resolution angle-resolved photoemission spectroscopy method in the energy range between 9.5 eV and 30.0 eV. The E(k) dependence was determined as well for bulk as for some of the surface states in the whole width of the valence band. Obtained results are compared with available calculated bulk band structure along Γ-L direction.

Opis:: Sn$\text{}_{0.96}$Gd$\text{}_{0.04}$Te has been studied by means of the resonant photoemission spectroscopy in the constant final states, constant initial states and energy distribution curves modes. In the constant final states spectrum of the well-known giant resonance at the 4d-4f threshold around 150 eV we were able to resolve a peak of the multiplet structure that has not previously been found. Spectra were also taken at the 4p-5d threshold around 280 eV revealing a double structure with antiresonating behaviour.

Opis:: Unreconstructed CdTe(100) surface prepared by ion bombardment and annealing is investigated by angle-resolved photoemission. The experimental band structure E(k$\text{}_{∥}$) is determined along high-symmetry lines of the surface Brillouin zone by measuring energy-distribution curves of photoelectrons. Different criteria were applied to separate surface and bulk related spectral features, e.g. calculating the position of bulk-derived emissions in the frame of the free-electron final state approximation assuming k conservation. In this way, most dispersing features could be explained. All remaining features were compared with theoretical surface band structures for different polar surface terminations which were calculated within a layer doubling procedure on the basis of an EHT-fit to the bulk band structure. The investigated CdTe(100)-(1×1) surface could be identified as Cd terminated. Two surface bands were observed, one located above the valence-band edge and the second in the open pocket of the projected bulk band structure along the Γ̅K̅ direction. At 4.6 eV binding energy an additional weakly dispersing band was found, which contains mixed surface and bulk character. The high density of bulk states associated with this edge of the heteropolar gap is also expected to contribute to this feature.
