    • Analysis of an Impedance Model for Porous Semiconductor Electrodes 

      Hansen, Johanna Etilde Marie (Master thesis, 2012)
      The main aim of this work was to analyze an impedance model for porous semiconductor electrodes consisting of spherical particles. The model should make it possible to analyze the flatband potential for this type of ...

    • Electrochemical and photoelectrochemical characterization of porous semiconducting electrodes 

      Tjelta, Morten (Doktoravhandlinger ved NTNU, 1503-8181; 2013:262, Doctoral thesis, 2013)
      CaNb2O6 particles with crystallite sizes from 24 to 64 nm have been produced by solgel synthesis. The flatband potential was by impedance measurements determined to be around -0.4 V vs. NHE for a bulk sample, which is in ...

    • Photoelectrochemical Hydrogen Production 

      Buan, Marthe Emelie Melandsø (Master thesis, 2012)
      The possibilities for using CaNb2O6 as a photocatalyst in direct water splitting have been evaluated by investigating the electronic structure of the material. In addition the oxide was doped with nitrogen in order to ...
