The ultrathin limit of improper ferroelectricity

Volume: 10, Issue: 1
Published: Dec 6, 2019
The secondary nature of polarization in improper ferroelectrics promotes functional properties beyond those of conventional ferroelectrics. In technologically relevant ultrathin films, however, the improper ferroelectric behavior remains largely unexplored. Here, we probe the emergence of the coupled improper polarization and primary distortive order parameter in thin films of hexagonal YMnO 3 . Combining state-of-the-art in situ...
