Abstract
Via first principles calculations and experiments, H. Dixit, H. M. Christen, V. R. Cooper, and co‐workers show, in article number 1500041, that the flat energy landscape between coexisting phases in strained BiFeO3 thin films leads to a reversible, strain‐induced phase transformation between the polymorphs under the application of an external electric field, leading to an enhanced piezoresponse.
Keywords: multiferroic BiFeO3 , phase coexistence, piezoelectric response, solid‐state nudged elastic band method
