Top-seeded solution growth method under high-oxygen-pressure atmosphere has been developed for obtaining high-performance and large-sized single crystals of ferroelectric (Bi0.5Na0.5)TiO3 (BNT). Crystals grown at 1000 °C at a Po2 of 0.9 MPa exhibited a well-saturated hysteresis with a remanent polarization of 34 μC/cm2 and a coercive field of 22 kV/cm along <100>cubic. The spontaneous polarization of BNT along <111>cubic is estimated to be 59 μC/cm2 from the measured polarization properties along <100>cubic of the crystals obtained. Domain observations using piezoresponse force microscopy revealed that the degraded performance of BNT crystals grown at a low Po2 is attributed to unswitched 71° domains remaining even after applying a high electric field to the crystals .

Rutile single crystals with high quality and high transparency were grown successfully by tilting-mirror-type floating zone (TMFZ) technique. The grown crystals were characterized by polarized optical microscopy, X-ray diffractometer, UV-visible spectrophotometer and etch pits density measurement. The effect of applied pressure during growth on the optical properties and defect density of the rutile crystals were investigated. It was found that the rutile crystals grown under the high oxygen pressure are bright and transparent due to the lower concentration of defects, but rutile crystals grown at ambient or lower oxygen pressure exhibit deep blue color due to presence of defects such as dislocations and grain boundaries. The crystals grown under high oxygen pressure contains no low-angle grain boundaries, indicating that it can be used for high efficiency optical devices.
