Reversible polarization switching in leaky ferroelectrics using an ionic gel induced electrostatic field effect

In this work, a transparent and free-standing ionic gel as the dielectric layer for polarization switching in leaky ferroelectric thin films is reported. By applying an electric field over liquid used electrostatic gated capacitor, one can avoid electronic conduction. The association of electrical double with depolarization at solid–liquid interface contributes to reversible PbZrxTi1−xO3 (x = 0.6) (PZT). Using such gels, anisotropic ferroelastic from mono-c-domain toward a-domain studied PZT grown on CaF2 substrates. Our results demonstrate that field, induced by gel, effective promising way investigate ferroelectrics.
