Abstract

The cryogenic transverse extensional and thickness shear properties of the (1 - x)Pb(Mg1/3Nb2/3)O3-xPbTiO3(PMN-xPT) single crystal with the optimal crystallographic directions were investigated in present work. With the temperature down to 78 K, a characteristic decrease in piezoelectric strain constants (d31, 2020-831 pC N-1and d15, 4114-2823 pC N-1) and compliance coefficients (s11E, 95.3-50.6 × 10-12m2N-1and s55E, 227-184 × 10-12m2N-1) was demonstrated. In comparison, the piezoelectric voltage constant (g31and g15) and electromechanical coupling coefficient (k31and k15) exhibits an almost temperature-independent behavior. Even at 78 K, high values of g31∼ 0.045 Vm N-1, g15∼ 0.057 Vm N-1, k31∼ 0.86, and k15∼ 0.94 can be obtained. Such superior low temperature piezoelectric performance is favorable for the cryogenic device designs and applications, especially for the hydrophones with high gijneeded.
