Abstract

Abstract: It is of great importance to accurately determine the full matrix parameters of the piezoelectric materials using as few samples as possible. Here we performed a simple and widely applicable method to accurately determine the full matrix parameters of [001]C -poled K(Ta, Nb)O3 single crystal. Only one sample was used throughout the experiment procedure, which eliminated inconsistency from multi-sample testing. We also improved the accuracy of results by inversing the impedance spectra of two inequivalent crystallographic directions, [001]C and [010]C . Based on this technique, variation of full matrix parameters with temperature were obtained using one sample. This work is of great significance for the characterization of novel piezoelectric materials and the evaluation of the performance of piezoelectric devices at various temperature.
