Query: Symmetry-driven atomic rearrangement at a brownmillerite-perovskite
  interface   Many of the recent advancements in oxide heterostructures have been
attributed to modification of spin, charge, lattice, and orbital order
parameters at atomically well-defined interfaces. However, the details on the
structural, chemical, and electrostatic evolution of interfaces comprised of
materials with different crystallographic symmetries remain to be understood.
In this work, we have mapped out the interfacial connectivity of atoms of two
dissimilar materials, the perovskite SrTiO3 and the brownmillerite SrCoO2.5,
using high resolution scanning transmission electron microscopy and geometric
phase analysis. We observed unique symmetry-mismatch driven atomic
displacements restricted to only the first few atomic layers, which can
critically modify the properties of the system. Provided that SrCoO2.5 is a
promising energy material due to its open framework structure, the improved
understanding of the interfacial structure on the atomic level can lead to the
rational design of novel oxide heterostructures.
