Abstrakt: Surface acoustic wave propagation in a 0.955Pb (Zn1/3Nb2/3)O3-0.045PbTiO3multidomain single crystal poled along [001]chas been analyzed theoretically using Christoffel wave equations. From the measured experimental data, the orientational dependence of surface acoustic wave phase velocities, electromechanical coupling coefficients and power flow angles was calculated. The results showed that surface acoustic wave propagations of 0.955Pb (Zn1/3Nb2/3)O3-0.045PbTiO3are poor than 0.93Pb(Zn1/3Nb2/3)O3-0.07PbTiO3crystal slightly. However, the 0.955Pb (Zn1/3Nb2/3)O3-0.045PbTiO3single crystals have higher rhombohedral-tetragonal phase transition temperature and much stabler electromechanical properties. This may expand applications range of SAW devices. [ABSTRACT FROM AUTHOR]
