The transport of charge across symmetrical low-angle [001] tilt grain boundaries in Fe-doped Sr Ti O 3 was examined. Grain boundary resistances were obtained from impedance spectroscopy measurements on bicrystals with misorientation angles θ= 2.3⁠, 5.4, and 7.8 as a function of temperature and oxygen partial pressure. By comparing these data with values predicted from a double Schottky-barrier model, we show that the resistance of a low-angle tilt grain boundary in acceptor-doped Sr Ti O 3 is correlated with its dislocation content, but in a nontrivial manner.
