dc.description.abstract | Na1/2Bi1/2TiO3-BaTiO3-K1/2Na1/2NbO3 (NBT-BT-KNN) is a promising candidate system for actuator applications in lead-free piezoelectric materials because of its large electric-field-induced strain. We were able to fabricate 96.9% dense 90NBT-5BT-5KNN (mol%) single crystals by the solid-state single crystal growth technique using sintered pellets and SrTiO3 seed crystals. The fabricated single crystals with a (001) direction exhibited high piezoelectric performance with a large strain of 0.67% and a high converse piezoelectric constant (S-max/E-max) of about 1670 pm/V at 4 kV/mm. These values are much higher than those previously reported for ceramics, 0.45% and 560 pm/V at 8 kV/mm, and for single crystals, 0.57% and 950 pm/V at 6 kV/mm, of the NBT-BT-KNN system. The measured piezoelectric properties are even comparable with those of lead-containing piezoelectric single crystals, which demonstrates high applicability of the fabricated NBT-5BT-5KNN single crystals for actuators.
