【 摘 要 】

A new piezoelectric single crystal, Sr₃Ga₂Ge₄O₁₄ (SGG), has been grown successfully by the vertical Bridgman method with crucible-sealing technique. SGG crystal up to 2â€�? in diameter has been obtained. The relative dielectric constants, the piezoelectric strain constants, elastic compliance constants and electromechanical coupling factors have been determined with resonance and anti-resonance frequencies method by using the impedance analyzer (Agilent 4294A). The results show that the piezoelectric strain constants and electromechanical coupling factors of SGG single crystal are higher than those of LGS single crystals making it a potential substrate material for surface-acoustic wave applications.
