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

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... View More
