“…37 The intensity of the Raman mode at 238 cm −1 increased gradually with temperature, whereas the intensity of the Raman mode centered at 279 cm −1 remained unchanged, indicating that the two peaks began to split significantly as temperature increased; this shows that the Polarized light microscopy (PLM) can be used to observe changes in the crystal phase structure system based on the domain wall and extinction angle. According to previous studies, 38 the domain structure of a crystal is affected by many factors, such as different orientation combinations, which significantly affect the domain structure. Meanwhile, the domain structure of the crystal at the microlevel will inevitably affect the piezoelectric properties at the macro level.…”

The electrical and optical properties of (001)-and (110)-oriented 0.73 Pb(Mg 1/3 Nb 2/3 )O 3 -0.27PbTiO 3 single crystals are systematically investigated at various temperatures, both of which present a series of ferroelectric phase transition processes. Dielectric performance measurements reveal that the ferroelectric phase transition occurs over a temperature range, rather than at one temperature point. By testing the ferroelectric hysteresis P-E curves as well as bipolar and unipolar electric field-induced strain S-E curves, the values of remnant polarization, coercive field, maximum strain, and converse piezoelectric constant d 33 * change considerably near the phase transition temperatures. Simultaneously, the 0.73PMN-0.27PT single crystals with (001)-and (110)-orientations under a low electric field show ultrahigh d 33 * values of 3540 and 2817 pm/V, respectively, which can be attributed to the electric field-induced monoclinic and orthorhombic phases, respectively. The series of ferroelectric phase transitions upon heating, that is, from rhombohedral ferroelectric to monoclinic/orthorhombic, followed by from monoclinic/orthorhombic to tetragonal, and finally from tetragonal to cubic paraelectric, are further investigated via polarized light microscopy and Raman spectroscopy.
