Abstract
Abstract
Alternating current (AC) polarization can significantly improve electrical and optical performance of ferroelectrics, but there is still no theoretical guidance on how to get the best AC polarization conditions. In this paper, dynamic scaling method is firstly used to the determine optimal AC polarization process, and high piezoelectric coefficients were obtained at a low electric field and a very short time. Results indicate that it is effective not only for Pb-based PMN-PT ceramics, single crystal and PZT ceramics, but also for lead-free BNT-BT ceramics. The dynamic scaling method is expected to provide great support for AC polarization for ferroelectric materials.
