Abstract

The present invention provides free-standing heterostructures including a layer of BiFeO3 and a layer comprising a perovskite over which the BiFeO3 is epitaxially grown. The layer comprising the perovskite has been released from a substrate upon which it was originally grown. Also provided are methods for forming the free-standing heterostructures, which may include transferring the free-standing heterostructures to other host substrates.
