The electromechanical properties of tetragonal BaTiO{sub 3} and PbTiO{sub 3} single crystals

Conference ·
OSTI ID:10180973
The velocities of propagation for longitudinal and transverse sound waves in various directions have been measured by Brillouin scattering on high-quality mono-domain single crystals of BaTiO{sub 3} and PbTiO{sub 3}. Using these velocities and also the dielectric permittivities measured by the impedance method and by Raman spectroscopy, a complete set of elastic stiffness moduli C{sub ijkl}, piezoelectric constants e{sub rij}, and dielectric permittivity {epsilon}{sub ij} has been determined at ambient temperature. Dependence of these electromechanical properties on orientation and frequency is presented for both materials and the physical implications will be discussed.
