Evidence of residual ferroelectric contribution in antiferroelectric lead-zirconate thin films by first-order reversal curves
نویسندگان
چکیده
In this study, two different methods have been used in order to characterize lead-zirconate antiferroelectric thin film elaborated by a modified sol-gel process: First-Order Reversal Curves (FORC) measurements and impedance spectroscopy coupled hyperbolic law analysis. Approaches at low high applied electric fields allow concluding on the presence of weak residual ferroelectric behavior even if contribution is not visible polarization-electric field loops. Moreover, phase seems switch only when cells no coalescence domains occurs due well distribution small clusters material. The main goal paper show that FORC analysis are very sensitive complementary methods.

Polarization reorientation in ferroelectric lead zirconate titanate thin films with electron beams
Ferroelectric domain patterning with an electron beam is demonstrated. Polarization of lead zirconate titanate thin films is shown to be reoriented in both positive and negative directions using piezoresponse force and scanning surface potential microscopy. Reorientation of the ferroelectric domains is a response to the electric field generated by an imbalance of electron emission and trapping ...
متن کاملLarge Electrocaloric Effect in Relaxor Ferroelectric and Antiferroelectric Lanthanum Doped Lead Zirconate Titanate Ceramics
Both relaxor ferroelectric and antiferroelectric materials can individually demonstrate large electrocaloric effects (ECE). However, in order to further enhance the ECE it is crucial to find a material system, which can exhibit simultaneously both relaxor ferroelectric and antiferroelectric properties, or easily convert from one into another in terms of the compositional tailoring. Here we repo...
متن کاملResidual stress effects on piezoelectric response of sol-gel derived lead zirconate titatnate thin films
Piezoelectric properties of three sol-gel derived Pb Zr0.53Ti0.47 O3 thin film specimens of different thicknesses integrated onto Pt/Ti/SiO2 Si substrates are investigated to delineate the influence of residual stress on the strain-field response characteristics from other thickness related effects. Residual tensile stresses are determined from wafer curvature measurements for films ranging in ...
