Abstract

The piezoelectric d coefficients of 〈111〉 oriented (1-x)Pb(Zn1/3Nb2/3)O3-xPbTiO3 single crystals for x = 0.045 and x = 0.08 (PZN-4.5%PT and PZN-8%PT) have been measured as functions of DC bias field and frequency using a Zygo laser interferometer system. The d coefficients decreased as the DC bias was increased, perhaps because of domain wall clamping due to the bias field. The d coefficients were also found to decrease with the increase of frequency; this frequency dependence decreased at sufficiently large bias fields. High d15 values (-2800 pC/N for PZN-4.5%PT and -3300 pC/N for PZN-8%PT) were measured, which may make these 〈111〉 oriented crystals promising candidates for high performance shear transducers.
