Research Interest:

As part of the „SFB 917 - Nanoswitches“ the oxygen diffusion in amorphous gallium oxide, GaOx, is examined. Since structure and stoichiometry have an influence on the material properties, this should be further investigated by SIMS analysis and the van der Pauw method.

Further research interests:

  • Resistive Switching
  • Pulsed Laser Deposition
  • Isotope exchange experiments
  • SIMS
  • van der Pauw experiments
