“…The domain walls almost disappeared, suggesting the emergence of a monodomain state. Our experimental results are consistent with the theorical calculation results reported by Xu et al [2,3,18,19]. Therefore, we propose that the decrease of domain walls density and ordered domain structure is beneficial to improve the crystal transmittance.…”

This study investigated the optical properties and the interband transition of a ternary [100]-oriented 6PSN-61PMN-33PT relaxor ferroelectric single crystal. Compared with the binary [100]-oriented PMN-32PT crystal, the [100]-oriented 6PSN-61PMN-33PT crystal exhibited excellent optical properties, including high transmittance, low refractive index, weak frequency dispersion, and low reflection and absorption coefficients. All these differences can be attributed to the structural changes of the 6PSN-61PMN-33PT crystal, such as its large lattice size and increased band gap. The crystal’s transmittance was significantly improved after alternating current electric field poling due to the increased domain size and the order domain structure. The largest transmittance for the 6PSN-61PMN-33PT crystal was up to 66%. Our experimental results indicate that the ternary 6PSN-61PMN-33PT ferroelectric single crystal has great application potential in the optical field.

“…Recently, it was reported that AC-poling can enhance both the dielectric and piezoelectric performance for relaxor-PT crystals. [26][27][28][29][30][31][32][33] Thus, it is expected that the piezoelectric properties for textured ceramics can be enhanced by the AC-poling. Figure 6A shows the P-E hysteresis loops of textured PMN-28PT ceramic with 1 vol.% BT templates from 1st to 10th cycle of AC electric field, and it can be seen that the E c significantly decreases from 1st to 3rd cycle of AC electric field, while it becomes stable from 4th to 10th cycle.…”

“…From the study of single crystals, the increase of dielectric and piezoelectric properties after AC-poling has been attributed to the increase in the domain size. 26,32,33 For textured PMN-28PT ceramics, the grain size is in the order of 10 μm, indicating that the domain size must be below 10 μm, which cannot be comparable to the domain size in AC-poled single crystals (could be on millimeter scale). Second, the grains are not exactly along the <001> direction in textured PMN-28PT ceramics, which may lower the enhancement effect of AC-poling on dielectric and piezoelectric properties.…”

“…In addition, many studies have shown that the technique of alternating current electric field poling (AC-poling) can enhance both the dielectric and piezoelectric performance of relaxor-PT crystals by 20-50%, when compared to the direct current electric field poling (DC-poling). [26][27][28][29][30][31][32][33] Due to the similarity between single crystals and textured ceramics, it is also necessary to investigate the impact of ACpoling on the dielectric and piezoelectric performances of textured ceramics.…”

Textured piezoelectric ceramics, such as textured Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 (PMN-PT) ceramics, have attracted considerable attention from both academia and industry, as they possess crystal-like piezoelectric properties, high composition homogeneity, and low manufacturing cost. However, the main difficulty with the textured piezoelectric ceramics is the presence of BaTiO 3 (BT) templates, which greatly reduces their piezoelectricity and phase transition temperature. Thus, it is highly recommended to fabricate textured piezoelectric ceramics using as few templates as possible. Here, we successfully fabricated high-quality <001>-textured PMN-28PT ceramics (texturing degree of 99%) by using an extremely small amount of BT templates (1 vol.%) with the help of CuO/B 2 O 3 sintering aids. The textured PMN-28PT ceramic exhibits 80% piezoelectric coefficient (d 33 ∼ 1200 pC/N), 96% electromechanical coefficient (k 33 ∼ 88%) and the same temperature stability (T rt ∼ 100, T c ∼ 150 • C) when compared to its single crystal counterpart. In addition, by using an alternating current electric field poling (AC-poling), the piezoelectric coefficient d 33 and dielectric permittivity ε 33 of the textured PMN-28PT ceramics were further enhanced around 5-8%. It is believed that the advantages of high electromechanical properties, low cost, and easy mass production of textured PMN-28PT ceramic will make it a promising candidate for advanced electromechanical devices.

DWs results in anomalous behavior in the material compared to the mono domain state. In relaxorferroelectrics such as Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 (PMN-PT) or Pb(In 1/2 Nb 1/2 )O 3 -Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 (PIN-PMN-PT), manipulating DWs has been shown to achieve excep tional dielectric and piezoelectric proper ties, lending them as excellent candidates for several electromechanical applica tions including sensors, actuators, energy storage, drug delivery, diagnostic imaging, and nondestructive testing. [4][5][6][7][8][9] Among several DW engineering methods to achieve further enhancement, the use of alternating current poling (ACP) to manipulate domains has received con siderable attention due to its convenience and effectiveness. [10][11][12][13][14][15][16] Studies have shown that up to 40% enhancement in piezo electric coefficient (d 33 ) and 35% enhance ment in free dielectric constants using ACP compared to conventional direct cur rent poling (DCP) methods. [10][11][12][13][14][15][16] However, even though the DW engineeringbased piezoelectric property enhancement is consistent for ACP, a consensus on how the domain size (or DW density) influences the piezoelectric properties is still not reached. Conventional belief in ferro electrics has been that the property enhancement is due to high domain wall density. [17][18][19] Studies by Chang et al., [11] Xu et al., [16] Zhang et al., [13] and Sun et al. [10] on PMN-PT single crystals (SCs) show that the presence of monoclinic phases and finer domain sizes as a result of ACP are responsible for piezoelectric property enhancement, indicating that the con ventional wisdom still holds for relaxorferroelectrics. However, Acting like thermal resistances, ferroelectric domain walls can be manipulated to realize dynamic modulation of thermal conductivity (k), which is essential for developing novel phononic circuits. Despite the interest, little attention has been paid to achieving room-temperature thermal modulation in bulk materials due to challenges in obtaining a high thermal conductivity switching ratio (k high /k low ), particularly in commercially viable materials. Here, room-temperature thermal modulation in 2.5 mm-thick Pb(Mg 1/3 Nb 2/3 )O 3 -xPbTiO 3 (PMN-xPT) single crystals is demonstrated. With the use of advanced poling conditions, assisted by the systematic study on composition and orientation dependence of PMN-xPT, a range of thermal conductivity switching ratios with a maximum of ≈1.27 is observed. Simultaneous measurements of piezoelectric coefficient (d 33 ) to characterize the poling state, domain wall density using polarized light microscopy (PLM), and birefringence change using quantitative PLM reveal that compared to the unpoled state, the domain wall density at intermediate poling states (0< d 33
