Opis:: We report on the first experimental observations of an anomalous increase in the resistance of a semiconductor-super conductor contact in the vicinity of the critical temperature T$\text{}_{c}$. The effect is found in lead-doped InSb thin films having inclusions of lead of 1-3 μm in diameter: The observed effect can be a model that explains similar resistance increase observed sometimes in the high T$\text{}_{c}$ superconductors.

Opis:: The energy spectrum of a quantum dot made from IV-VI narrow gap semiconductors is studied. The calculations of the energy levels as functions of the dot radius are performed. When the anisotropy of the bare energy spectrum is strong, the energy levels are calculated using Fal'kovskii's adiabatic approximation for multiband systems. When the quantum dot material has an inverted band gap with respect to the host, the low-energy states within the fundamental gap are shown to arise.

Opis:: An anomaly of the in-plane conductivity is observed in the superlattices PbTe/SnTe on (001)KCl in the temperature region of 60-130 K. The anomaly is caused by a structural phase transition in SnTe layer and as a result, the transition induced formation of defects. These defects are additional scattering centres which decrease the superlattice conductivity.

Opis:: A comparative study of structural and superconductive properties of semi conductor epitaxial superlattices PbTe-SnTe and PbTe-PbS grown on (001) KCl has been carried out. It has been found that the superconductivity of the PbTe-SnTe superlattices is caused by the stretching strain in the SnTe layers and it may be connected with the relative positions of L$\text{}_{8}^{+}$ and L$\text{}_{6}^{+}$ terms of PbTe and SnTe, respectively in the heterojunction. In contrast to the PbTe-SnTe superlattices, the superconductivity of the PbTe-PbS super lattices is found to be associated with regular misfit dislocation grids which are generated at the interfaces.
