“…The ceramic samples are usually cut to a thickness equal to or below 1 mm and polished in order to obtain a flat surface for the PFM investigation [43][44][45][46][47]. Firstly, grinding with silicon carbide grinding papers (5-20-µm-large SiC particles) is reported [44,48], followed by polishing on a fabric using a polishing paste with a gradual decrease in the size of the diamond abrasive down to 0.25 µm [44,[48][49][50][51][52][53][54] and finishing with a colloidal SiO 2 suspension containing particles just a few tens of nanometres in size [33,44,48,[51][52][53][54][55]. Finally, for removing the SiO 2 particles from the surface, distilled water can be used.…”

“…In the case of lead-based ceramics, PFM analyses of domain structures were performed in PbTiO 3based [68][69][70] [33] and Pb(Fe 1/2 Nb 1/2 )O 3 -based [80] ceramic samples. The domain structures in lead-based ceramic samples vary significantly, from typical macro-sized domains [33,49,56,68,69] in ferroelectrics to polar nano-domains (PNDs) in relaxors [33,53,71,72,74], which are often called labyrinth-type [71,72] or finger-print nanoscale domains [53] or nanoscale quasi-regular maze domains [53,74].…”

In recent years, ferroelectric/piezoelectric polycrystalline bulks and thick films have been extensively studied for different applications, such as sensors, actuators, transducers and caloric devices. In the majority of these applications, the electric field is applied to the working element in order to induce an electromechanical response, which is a complex phenomenon with several origins. Among them is the field-induced movement of domain walls, which is nowadays extensively studied using piezoresponse force microscopy (PFM), a technique derived from atomic force microscopy. PFM is based on the detection of the local converse piezoelectric effect in the sample; it is one of the most frequently applied methods for the characterization of the ferroelectric domain structure due to the simplicity of the sample preparation, its non-destructive nature and its relatively high imaging resolution. In this review, we focus on the PFM analysis of ferroelectric bulk ceramics and thick films. The core of the paper is divided into four sections: (i) introduction; (ii) the preparation of the samples prior to the PFM investigation; (iii) this is followed by reviews of the domain structures in polycrystalline bulks; and (iv) thick films.

“…Nonetheless, while considerable work has been dedicated to the study of the extrinsic effects of domain walls on the functional response of such materials, comparatively fewer discuss the effects of domain walls on the relaxor-FEs' local electromechanical response. [45,46] Herein, we consider the influence of proximity to domain walls on the local piezoresponse in a relaxor-FE solid solution material. Specifically, switching behavior in a [001]-cut tetragonal 0.60PbðMg 1=3 Nb 2=3 ÞO 3 À 0.40PbTiO 3 (0.60PMN-0.40PT) single crystal is investigated through use of resonant piezoresponse force microscopy (R-PFM, as described in Figure S1, Supporting Information).…”

Domain walls' vibration and motion contribute significantly to the exceptionally large dielectric and piezoelectric response of ferroelectric materials. Yet, the specific length scales at which domain walls impact characteristic parameters remain largely unprobed. Previous studies examining correlation of domain wall proximity and functional response at the micrometer or submicrometer scales are often based on (locally or globally) "written" domains. The stability of such domains can be affected by many factors, resulting in convoluted effects of domain wall proximity and their stability when studying the local functional response. Herein, the effects of preexisting domain walls on the nanoscale polarization switching in a [001]-cut relaxor-ferroelectric 0.60PbðMg 1=3 Nb 2=3 ÞO 3 À 0.40PbTiO 3 single crystal are probed by piezoresponse force microscopy. It is found that domain wall proximity has limited impact on polarization switching for locations ⪝300 nm away. While a transition from a growth-to nucleation-limited regime and/or change in dimensionality of domain growth is possibly observed, the effective impact on nucleation voltage does not exceed 25% variation. These results are consistent with the well-documented pervasive chemical, polar, and structural heterogeneities present in relaxor-ferroelectrics and the resulting "soft" piezoelectric behavior.
