“…High-performance piezoelectric materials play a vital role in modern technology and scientific research. [1][2][3][4][5][6][7] Perovskite ferroelectric materials have been widely used in electromechanical devices due to their excellent piezoelectric properties. [8] Compared with traditional Pb(Zr,Ti)O 3 (PZT) ceramics, the relaxor ferroelectric single crystals, for example, PMN-PT crystals, possess ultrahigh piezoelectric coefficient d 33 of 1200-2500 pC N −1 and the electromechanical coupling coefficient k 33 of 90-94%, greatly enriching the application scenarios of piezoelectric materials.…”

Relaxor‐PbTiO3 crystals exhibit excellent piezoelectric properties (d33 > 2000 pC N−1 and k33 > 90%) and thus attractes widespread attention in the past two decades. However, the inevitable segregation of components during the crystal growth results in relatively low‐performance consistency of Pb(Mg1/3Nb2/3)O3‐PbTiO3 (PMN‐PT) crystals, which seriously affects their practical applications. In this work, Nd3+ as A‐site substitution is introduced to improve the uniformity of electromechanical performance of PMN‐PT crystal. The results show that the crystal exhibits a high piezoelectric coefficient of 3000 pC N−1 in rhombohedral phase with a variation of 36%. The electron probe X‐ray microanalyzer indicates that the opposite separation characteristics of Nd3+ and Ti4+ lead to improved uniformity of piezoelectric performance along the crystal boule. The giant piezoelectricity in Nd‐doped PMN‐PT is attributed to the enhanced local structural heterogeneity introduced by doping Nd. Furthermore, the Nd‐doped PMN‐PT crystal shows the rhombohedral‐tetragonal phase transition temperature in the range of 74–87 °C, which indicates that Nd‐doped PMN‐PT crystal can be a promising candidate for the design of advanced piezoelectric transducers.

“…The output power density of 0.45 W/cm 3 was three times larger than those of a PZT ceramic motor and a face-shear relaxor-PT crystal motor. The reason for the enhancement was the low thermal generation, and in particular, it is ascribed to the "hardening effect" induced by dipole-defects arising from Mn-modification [217]. The anisotropic characteristic of relaxor-PT single crystal also offers better performance in the design of actuators [213,214].…”

Numerous investigations on the development of the relaxor-PbTiO3 ferroelectric crystals have been carried out since their extraordinary properties were revealed. Recent developments on these crystals have offered further advances in electromechanical applications. In this review, recent developments on relaxor-PbTiO3 crystals and their practical applications are reviewed. The single crystal growth methods are first discussed. Two different strategies, poling and doping, for piezoelectric improvement are surveyed in the following section. After this, the anisotropic features of the single crystals are discussed. Application perspectives arising from the property improvements for electromechanical devices are finally reviewed.
