The core structures of two types of <001> {110} edge dislocations in BaTiO3 have been observed and investigated at the atomic scale by using aberration-corrected transmission electron microscopy (AC-TEM). The edge dislocations are both dissociated into two collinear partial edge dislocations bounding a complex stacking fault (SF). While the partial dislocations have the same Burgers vector, 12[001], the dissociation planes are different for the two types of edge dislocations, with one at the BaO plane and the other at the TiO2 plane. The SF energy has been estimated by measuring the SF width
