Research interest

  1. Melt and flux growth of oxides and fluorides for optical, piezoelectric and laser crystals, and as substrates for novel electronic devices.
  2. Growth and characterization of wide-bandgap semiconductor bulk crystals. These crystals are used as substrate material in semiconductor technology.
  3. Growth and characterization technologies, correlation between preparation and properties of bulk single crystals in a general sense.
