TEMPERATURE AND FIELD STABLE RELAXOR-PT PIEZOELECTRIC SINGLE CRYSTALS |
| 摘要 |
The application is directed to piezoelectric single crystals having shear piezoelectric coefficients with enhanced temperature and/or electric field stability. These piezoelectric single crystal may be used, among other things, for vibration sensors as well as low frequency, compact sonar transducers with improved and/or enhanced performance. |

1. A piezoelectric single crystal having a composition with the formula yPb(In1/2Nb1/2)O3-(1-y-z) Pb(Mg1/3Nb2/3)O3-zPbTiO3 (“yPIN-(1-y-z)PMN-zPT”), where 0.26≦y≦0.50, 0.31<z≦0.36 and wherein the crystal is poled along the crystallographic [110] direction, the crystal having an orthorhombic/monoclinic phase and ‘1O’ single domain state. |
