Popis: | Complete sets of elastic, dielectric, and piezoelectric properties of flux grown rhombohedral Pb(Zn1/3Nb2/3)O3–xPbTiO3 (PZN–PT; $x =0.0475$ , 0.055, and 0.065) single crystals poled along [001] crystal direction have been determined in the present work. Their phase transformation temperatures, coercive fields, and mechanical quality factors are also provided. The results show that [001]-poled rhombohedral PZN–PT single crystals exhibit superior longitudinal piezoelectric properties ( $k_{33} \ge0.90$ , $d_{33} \approx 1580$ –2500 pC/N). While the piezoelectric properties increase with PT content, the $T_{\mathrm{ RT}}$ and hence temperature stability of the crystal degrade accordingly. These unique properties, together with the property matrices provided in this work, can be used advantageously to design high-performance piezoelectric devices of longitudinal activation/sensing mode to suit various application needs. |
