Abstract

We have successfully grown high quality piezoelectric single crystals of Sr₃NbGa₃Si₂O₁₄ (SNGS) and Sr₃TaGa₃Si₂O₁₄ (STGS) by the Czochralski technique. The piezoelectric stress constant epsiv₁₁ and dielectric permittivity epsiv₁₁ as well as elastic constants C₁₁ ^E and C₆₆ ^E were determined at temperatures up to 930degC for both crystals.
