Crystal Growth and Thin Film Deposition of High Performance Piezoelectrics

Abstract

Piezoelectric single crystals in the lead ytterbium niobate-lead titanate and BiScO3-PbTiO3 systems were grown and characterized as high temperature piezoelectrics. The properties were quite good, with d33 coefficients as high as 2500 pm/V in PY N-PT. Epitoxial and fiber textured thin films were prepared by pulsed-laser deposition and chemical solution deposition, respectively. These films show the highest reported e31,f coefficients for high Tc films. In addition, it was determined that the amplitude dependence of the dielectric and piezoelectric response of the films can be described using a frequency-dependent Rayleigh approach.
