      abstract     = {The present study investigates the impact of point defect
                      concentrations on the equilibrium crystal shape of strontium
                      titanate. Therefore the shape of intergranular pores in
                      coarse microstructures was observed. The point defect
                      concentration was changed by donor-doping with Niobium (0.2
                      $at.\%–2.4$ $at.\%).$ A decreasing surface energy
                      anisotropy was found with increasing donor dopant
                      concentration and with increasing temperature. These
                      findings are correlated to the defect chemistry and grain
                      growth behavior of strontium titanate.},
