Ferroelectric or non-ferroelectric: Why so many materials exhibit “ferroelectricity” on the nanoscale [PDF]

Applied Physics Reviews, 2017
Ferroelectric materials have remained one of the major focal points of condensed matter physics and materials science for over 50 years. In the last 20 years, the development of voltage-modulated scanning probe microscopy techniques, exemplified by Piezoresponse force microscopy (PFM) and associated time- and voltage spectroscopies, opened a pathway to

Ferroelectrics as Smart Mechanical Materials [PDF]

Advanced Materials, 2017
The mechanical properties of materials are insensitive to space inversion, even when they are crystallographically asymmetric. In practice, this means that turning a piezoelectric crystal upside down or switching the polarization of a ferroelectric should not change its mechanical response.
