Title: Evolution of structure in Na 0.5 Bi 0.5 TiO 3 single crystals with BaTiO 3

The structural, dielectric, and piezoelectric properties of Na0.5Bi0.5TiO3-x mol. %BaTiO3 (NBT-x%BT) crystals have been investigated. The dielectric and piezoelectric properties of NBT-x%BT were enhanced near x¼5–7. High resolution synchrotron x-ray powder diffraction studies revealed the presence of a phase boundary between monoclinic (Cc) and tetragonal (P4bm) phases near x¼5–7, where the dielectric and piezoelectric properties were enhanced.
