Core structures of <001> {110} edge dislocations in BaTiO3

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 b...
