Abstract

La₃Ga_5.5Nb_0.5O₁₄ crystals are promising materials for bulk acoustic wave and surface acoustic wave applications. In this work, the starting materials for high quality La₃Ga_5.5Nb_0.5O₁₄ single crystal growth were investigated. Adding extra Ga₂O₃ of 1.0-1.5 wt% to the starting materials was found to be beneficial for high quality crystal growth. High quality La₃Ga_5.5Nb_0.5O₁₄ crystals were grown by the conventional Czochralski method along the X- and Z-axes. Complete sets of dielectric constants, piezoelectric coefficients and elastic constants of La₃Ga_5.5Nb_0.5O₁₄ crystals grown along the X- and Z-axes were determined by a resonance technique and impedance analysis at room temperature, respectively. The relevant constants were obtained and discussed. The obtained results for La₃Ga_5.5Nb_0.5O₁₄ are: ε₁₁^T = 19.07, ε₃₃^T = 79.06, d₁₁ = - 7.00 pC/N, d₁₄ = 5.60 pC/N; s₁₁^E=9.60 pm²/N; s₁₂^E=-4.65 pm²/N; s₁₃^E=-2.05 pm²/N; s₁₄^E=-3.60 pm²/N; s₃₃^E=5.77 pm²/N; s₄₄^E=23.60 pm²/N and s₆₆^E=28.50 pm²/N, respectively.
