Abstract

The dielectric and piezoelectric constants of single crystal barium titanate have been theoretically calculated and experimentally measured for different cutting orientation directions. The dielectric constant rapidly increases as the cutting direction deviates away from the unique spontaneous polarization direction [001]. The effective piezoelectric strain constant d₃₃ exhibits the same trend in the range from 0° to 50° away from the polarization direction and has the maximum value more than 3.5 times larger than its value along the polarization direction. The electromechanical coupling factor k₃₃ is also enhanced by choosing a cutting direction canted away from the polarization direction.
