Current Research

  • Quantization of spin waves and acoustic waves in nanostructures.

  • Spin waves in ferromagnetic nanowires and thin films.

  • Elastic properties of nanostructured materials.

  • Velocity angular dispersion of surface acoustic waves on semiconductors (e.g. Si, InSb, GaAs) and other materials (e.g. SAW-device substrates LiTaO3 and LiNbO3).

  • Surface and bulk acoustic modes in passivated porous silicon.

  • Ferroelectric and ferroelastic phase transitions.
