摘要：

We discuss the recent proposal by Klie [Phys. Rev. B 68, 214101 (2003)] that a Thomas-Fermi screening model provides a better description of grain-boundary potentials in acceptor-doped SrTiO(3) than the established double-Schottky-barrier model. We point out several inconsistencies between the model predictions and experimental observations.
