Layer selective control of the lattice structure in oxide superlattices

Adv Mater. 2014 Jan 15;26(2):258-62. doi: 10.1002/adma.201303483. Epub 2013 Oct 24.


A combined synchrotron X-ray diffraction and transmission electron microscopy study reveals a structural phase transition controlled by the overall thickness of epitaxial nickelate-aluminate superlattices. The transition between uniform and twin-domain states is confined to the nickelate layers and leaves the aluminate layers unaffected.

Keywords: X-ray diffraction; crystal structure; nickelates; superlattices; transition-metal-oxide heterostructures.
