Shear resonance behavior of single-domain PZN-PT single crystals.
The shear resonance behavior of rectangular-shaped samples of single-domain PZN-PT single crystal samples of 3m symmetry and having three faces parallel to the (111), (112), and (110) crystal planes has been examined. Sample geometries with separable resonance peaks are identified, which give shear properties consistent with 3m symmetry, namely, k15 approximately k24 and d15 approximately d24. Sample geometries with inseparable resonance peaks are also distinguished. The latter sample geometries are not suitable for shear property characterization of piezoelectric single crystals of 3m symmetry as the broad coupled resonance peak often results in inflated k15 and d15 values.
