Major research interests

  • Thermoelectric materials;
  • Computational materials science based on the density functional theory (DFT);
  • Rare earth based compounds;
  • Higher borides RB4, RB6 and RB12;
  • Anomalous diamagnetic susceptibility in transition metal compounds.

As a member of the Thermoelectric Materials Group Andrei investigates thermoelectric properties of Ruddlesden-Popper CaO(CaMnO3)m n-type compounds in the framework of the DFT approach. My main efforts are focused on discovering ways of manipulating thermoelectric properties by doping and altering the planar density of CaO/CaMnO3 interfaces.
