TL;DR: It is demonstrated that domain wall profile shapes are ultimately sensitive to the nature of the order parameter in the material, including the functional form of Ginzburg-Landau-Devonshire expansion, and numerical value of the corresponding parameters.

TL;DR: In this paper, the free energy of a thin ferroelectric film covered by a screening charge layer of different nature and calculate hysteresis loops of polarization and screening charge in the system at different temperatures was investigated.

TL;DR: Variable temperature electrochemical strain microscopy has been used to study the electrochemical activity of Sm-doped ceria as a function of temperature and bias and strongly non-monotonic dependence of relaxation behavior on temperature is interpreted as evidence for water-mediated mechanisms.

TL;DR: A multifrequency spectroscopy and spectroscopic imaging mode, referred to as general dynamic mode (GDM), that captures the complete spatially- and stimulus dependent information on nonlinear cantilever dynamics in scanning probe microscopy (SPM), which is expected to be useful for separating the contribution of different physical phenomena in the cantilesver response and understanding the role of cantilevers in dynamic AFM techniques.

TL;DR: Piezoresponse force microscopy (PFM) was originally developed as a technique to study electromechanical phenomena in ferroelectric perovskites on the nanoscale as mentioned in this paper.
