A relaxor-PT based piezoelectric crystal is disclosed, comprising the general formula of (PbM){[(M,M)(M,M)]Ti}O, wherein: M is a rare earth cation; Mis selected from the group consisting of Mg, Zn, Yb, Sc, and In; Mis Nb; Mis selected from the group consisting of Mg, Zn, Yb, Sc, In, and Zr; Mis Nbor Zr; 0&#x3c;x&#x2264;0.05; 0.02&#x3c;y&#x3c;0.7; and 0&#x2264;z&#x2264;1, provided that if either Mor Mis Zr, both Mand Mare Zr. A method for forming the relaxor-PT based piezoelectric crystal is disclosed, comprising pre-synthesizing precursor materials by calcining mixed oxides, mixing the precursor materials with single oxides and calcining to form a feeding material, and growing the relaxor-PT based piezoelectric crystal having the general formula of (PbM){[(M,M)(M,M)]Ti}Ofrom the feeding material by a Bridgman method.

Polar nanoregions engineered relaxor-PbTiOferroelectric crystals

Embodiments of the invention can be directed to controlling and/or engineering the size and/or volume of polar nanoregions (PNRs) of ferroelectric polycrystalline material systems. Some embodiments can achieved this via composition modifications to cause changes in the PNRs and/or local structure. Some embodiments can be used to control and/or engineer dielectric, piezoelectric, and/or electromechanical properties of polycrystalline materials. Controlling and/or engineering the PNRs may facilitate improvements to the dielectric, piezoelectric, and/or electromechanical properties of materials. Controlling and/or engineering the PNRs may further facilitate generating a piezoelectric material that may be useful for many different piezoelectric applications.
