“…However, materials having a large induced polarisation compared to the spontaneous polarisation have a strain predominantly quadratic as a function of the applied ac voltage. 330 Results from this study showed a significantly higher second harmonic response for soda-lime glass compared to PZT, indicating that the voltage-induced strain in soda-lime is predominantly due to an induced polarisation. Combining VPFM and LPFM also distinguished between PZT and the soda-lime glass, since vertical and lateral piezoreponses on polycrystalline PZT have a similar amplitude; in contrast, induced dipoles in the amorphous soda-lime glass align along the applied electric field direction, leading to a very low lateral response.…”

Piezoresponse force microscopy (PFM) probes the mechanical deformation of a sample in response to an electric field applied with the tip of an atomic force microscope. Originally developed more than two decades ago to study ferroelectric materials, this technique has since been used to probe electromechanical functionality in a wide range of piezoelectric materials including organic and biological systems. PFM has also been demonstrated as a useful tool to detect mechanical strain originating from electrical phenomena in nonpiezoelectric materials. Paralleling advances in analytical and numerical modelling, many technical improvements have been made in the last decade: switching spectroscopy PFM allows the polarisation switching properties of ferroelectrics to be resolved in real space with nanometric resolution, while dual ac resonance tracking and band excitation PFM have been used to improve the signal-to-noise ratio. In turn, these advances have led to increasingly large multidimensional data sets containing more complete information on the properties of the sample studied. In this review, PFM operation and calibration are described, and recent advances in the characterisation of electromechanical coupling using PFM are presented. The breadth of the systems covered highlights the versatility and wide applicability of PFM in fields as diverse as materials engineering and nanomedicine. In each of these fields, combining PFM with complementary techniques is key to develop future insight into the intrinsic properties of the materials as well as for device applications.

“…Ferroelastic stress-strain hysteresis curves for unpoled PZT 40,45,47,49,55, and 60 specimens at 25, 200, and 400 °C are presented in Figure 3. It is apparent that with increasing temperature there is a corresponding decrease in the coercive stress, maximum strain, and remanent strain in all compositions.…”

“…For fixed boundary conditions this tensor can be expressed and measured through derivative of dielectric stiffness with stresses. 4,5 However, this derivative depends on the constraints at the specimen boundaries. The electrostriction tensor ␥ iklm ͑or Q iklm ͒ can therefore vary from one experimental setup to another.…”

The apparent deformation due to an electric field does not rigorously describe the electrostriction phenomenon. This is in part due to uncertainties in the mechanical constraints at the specimen boundaries. Such constraints are very critical in thin films. Determining the electric-field-induced stress seems to be a more adequate approach to electrostriction. General thermodynamic considerations identify the electrostriction stress through strain derivatives of the dielectric displacement. Consequently, the derivatives of the dielectric coefficients are termed the electrostriction parameters. The strain-dielectric response of a material, which is called dielectrostriction, provides an avenue to study electrostriction. However, controlling the mechanical boundary conditions of a thin-film specimen can be challenging. This problem can be overcome by using a proposed planar capacitor sensor which does not require any mechanical contact with the specimen. The theoretical background and experimental results for the dielectrostriction study of a uniaxially loaded specimen are presented and discussed.
