abstract = {High-resolution transmission electron microscopy is often
used to characterize grain boundaries, but it is usually
limited to special high symmetry boundaries with a high
density of coincident sites. For these ‘special’
boundaries, both crystals can be brought into a low-index
zone-axis with the boundary plane parallel to the incident
electron beam. In this case the atomistic structure of the
boundary can be solved, which is not possible for other,
more general grain boundaries. In the present study, general
grain boundaries in SrTiO3 were analyzed using
aberration-corrected transmission electron microscopy and
scanning transmission electron microscopy. These boundaries
included at least one type of disconnection (i.e., defects
that can have a step and/or a dislocation component). Since
the dislocation component of disconnections along general
grain boundaries cannot be fully resolved using the methods
currently available, a plane matching approach was used to
compare disconnections at different boundaries. Using this
approach, the dislocation component of the disconnections
was partially characterized and was found to have an edge
component mainly parallel to {100} and {110}, close to
normal to the macroscopic grain boundary plane. The step
component of the disconnections was found to be aligned
mainly parallel to the same crystallographic planes ({100}
and {110}).},
