| Abstract Scope |
Interfacial interactions between dissimilar crystalline materials at heterointerfaces provide a route to stabilize novel electronic, magnetic and optical states not found in the bulk material systems. To realize theoretical predictions of exotic phenomena in bismuthate-based heterostructures including interfacial conductivity and superconductivity we investigate the atomic-scale structure formed between atomically-thin BaBiO3, a parent superconducting compound and perovskite titanate layers grown by oxide molecular beam epitaxy. Using a combination of in-situ reflection high energy electron diffraction measurements, Raman spectroscopy and synchrotron X-ray diffraction imaging, we find that at interfaces formed with ferroelectric tetragonal BaTiO3 in BaBiO3/BaTiO3 superlattices, polar structural distortions are induced in the BaBiO3 in addition to the suppression of a structural breathing distortion associated with insulating behavior in bulk BaBiO3. |
