      Bisquert, Juan; Ofir, Ashi; Dor, Snir; Grinis, Larisa; Zaban, Arie; Dittrich, Thomas American Institute of Physics (2008)
      The electron diffusion coefficient at varying porosity has been determined in a series of nanostructured TiO2 films of different initial thicknesses. The porosity was changed by applying different pressures prior to ...
