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.
