Description

Simulated position averaged convergent beam electron diffraction (PACBED) patterns of octahedral tilts in GdTiO3 along [110], with corresponding structures. Top-left shows theoretical undistorted structure; top-right contains in-phase octahedral rotations along [001]; bottom-left contains out-of-phase octahedral rotations along [110]; bottom-right contains both in-phase and out-of-phase tilts, as seen in the bulk structure.
