In situ total strain measurements revealing the strain mechanism of Pb(Mg1/3Nb2/3)O3PbTiO3 single crystals

Electrical performance and ferroelectric phase transition characteristic in different oriented 0.73PMN‐0.27PT single crystals

“…As temperature increased, the crystal phase changed from rhombohedral to cubic paraelectric, which did not result in a significant increase in the negative strain, which occurred in (001) pc . This result is consistent with the findings of Kim et al 23 The following were observed based on the comparison between different orientations: First, the relaxation phenomenon was more evident in the (110)oriented crystal; second, the (110)-oriented crystal exhibited worse symmetry than the (001)-oriented crystal, and the maximum negative strain on the right side of the Y-axis was greater than that on the left side at high temperatures.…”

Orientation-tunable ferroelectric and energy storage properties in PMN–PT single crystals

“…Because spontaneous polarization lies along the [111] direction, the polarization direction of the (111)-oriented PMN–PT agrees with the spontaneous polarization direction on poling along the [111] direction. 33…”

“…Because spontaneous polarization lies along the [111] direction, the polarization direction of the (111)oriented PMN-PT agrees with the spontaneous polarization direction on poling along the [111] direction. 33 Orientation-dependent polarization behaviors of PMN-PT single crystals were measured at 25 °C with 10 Hz frequency under E = 10 kV cm −1 . As shown in Fig.…”

Less than mm2 macrosymmetry in polarized (011)-oriented relaxor-PbTiO3 single crystals reflected in the face shear properties

“…1 Recently, much attention has been paid to (011)-oriented relaxor-PbTiO 3 single crystals with their unique anisotropic piezoelectric properties, i.e., d 32 along the crystallographic direction [100] is negative, while d 31 along the [011] is positive, which are highly beneficial for many practical applications. [2][3][4][5][6][7][8] For example, these unique anisotropic piezoelectric coefficients give a rise to a superior face-shear piezoelectric coefficient d 0 36 (the prime symbol denotes the corresponding value after in-plane rotation around the [011] axis), because d 0 36 is defined by the difference between d 31 and d 32 , being maximized at 6 45 rotation. 9,10 From the application point of view, a full set of property matrices is to be determined as accurate as possible for best-designing piezoelectric devices.…”
