RESEARCH

  • Theoretical calculations of point defect related luminescence, defect complexes, and carrier compensation in wide band gap semiconductors
  • Lattice thermal conductivity of complex metal oxides and their nanostructures
  • Nanoscaling approaches to thermoelectricity by computing both lattice and electronic parts of thermal conductivity
  • Molecular dynamics modeling of plasticity in nanowires and their strengthening mechanisms
