“…Similarly, resonant tunneling could be at the origin of the oscillations observed in the I-V curve at high voltages in Ref. 59. However, these experimental curves do not show clear NDR and the oscillations are clearly weaker than in our calculations.…”

“…Therefore, we argue that, in these particular instances presented in Fig. 4, the DW length is a primary factor, but this may not always be the case, and charged versus uncharged DW fractions might be a predominant factor in other cases ( 27 ). …”

“…Moreover, domain configurations can be highly complex and may not be resolved fully by the PFM measurements alone. This is especially true for variations in the polarization configuration through the thickness of the film, which can be elucidated using techniques such as spherical aberration–corrected transmission electron microscopy ( 27 , 32 ). …”

Ferroelectric materials have remained one of the foci 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 explore these materials on a single-digit nanometer level. Consequently, domain structures, walls and polarization dynamics can now be imaged in real space. More generally, PFM has allowed studying electromechanical coupling in a broad variety of materials ranging from ionics to biological systems. It can also be anticipated that the recent Nobel prize 1 in molecular electromechanical machines will result in rapid growth in interest in PFM as a method to probe their behavior on single device and device assembly levels. However, the broad introduction of PFM also resulted in a growing number of reports on nearly-ubiquitous presence of ferroelectric-like phenomena including remnant polar states and electromechanical hysteresis loops in materials which are non-ferroelectric in the bulk, or in cases where size effects are expected to suppress ferroelectricity. While in certain cases plausible physical mechanisms can be suggested, there is remarkable similarity in observed behaviors, irrespective of the materials system. In this review, we summarize the basic principles of PFM, briefly discuss the features of ferroelectric surfaces salient to PFM imaging and spectroscopy, and summarize existing reports on ferroelectric-like responses in non-classical ferroelectric materials. We further discuss possible mechanisms behind observed behaviors, and possible experimental strategies for their identification.3
