| 摘 要： | 研究了掺镧锆锡钛酸铅反铁电陶瓷在单脉冲方波电压激励下的极化反转特性。分析了1Hz正弦交变电压和上升前沿约为1ns单脉冲方波电压激励下样品的电滞特征以及不同脉冲宽度下样品的极化反转行为。讨论了样品的反铁电-铁电相变时间。结果表明:单方波脉冲电压激励下,样品的正向开关电场增加,反向开关电场减小;样品完全极化反转所需时间为394ns,使样品开始极化反转的最小脉冲宽度在50～100ns之间。

| Abstract: | The polarization switching property of antiferroelectric materials La-doped Pb(Zr,Sn,Ti)O3 stimulated by monopulse rectangle voltage was investigated. The electronic hysteresis loop characteristics of the ceramic samples excited by 1 Hz-sine alternating voltage and monopulse rectangle voltage with different pulse widths were measured and analyzed. And the phase transition time of the ceramic samples was discussed. Compared with 1 Hz-sine alternating voltage, forward electric switching field increases and backward switching electric field decreases when monopulse voltage is applied. Under monopulse voltage, forward switching time is 394 ns. The minimum pulse width which results in the beginning of polarization switching is in the range of 50-100 ns. |
