Electronic structure and anomalous physical properties of metastable Al-Si solid solutions

Al-Si solid solutions synthesized under high pressure demonstrate striking physical properties, such as enhanced superconductivity and peculiarities of low-temperature transport coefficients. In order to understand the connection of these effects to the electronic structure changes we have performed a first-principles study of the electronic spectra and Fermi surfaces of Al-Si solid solutions. We show that two electronic topological transitions (ETT's) lead to unusual concentration dependencies of the resistivity, thermoelectric power and Hall constant of the system while a variety of other interesting phenomena such as lattice instability and superconductivity enhancement may be a result of the nesting features appearing upon Si doping. We present also the results of our theoretical calculations of the thermodynamic and transport properties of Al-Si solid solutions which are in good agreement with experiment and reproduce nicely the experimentally observed peculiarities.

Different Detector Types Used in Plasma Physics Experiment

We analyzed the possibility of using different detector types (semiconductor, scintillator, thermoluminescent, nuclear emulsions) for plasma diagnostics. We investigated the main characteristics of such detectors, on the basis of which an X-ray spectrometer complex was created.
