      abstract     = {By performing in situ growth studies during pulsed laser
                      deposition, we observed a strong reduction of the surface
                      diffusion coefficients for slightly non-stoichiometric
                      SrTiO3. Both, stoichiometric and non-stoichiometric thin
                      films exhibit 2D layer by layer growth. However, in the
                      non-stoichiometric case the 2D island coalescence is
                      significantly delayed, which goes along with a shift of the
                      reflection high electron energy diffraction (RHEED) minimum.
                      We could explain this shift of the RHEED minimum by
                      developing a model for the step density evolution taking
                      into account finite surface diffusion.},
