Sol–gel derived Pb(Zr,Ti)O3 thin films: Residual stress and electrical properties
نویسندگان
چکیده
Pb(Zr,Ti)O3 compositions are under investigation for applications that include integrated capacitors, piezoelectric sensors, and actuators. Sol–gel synthesis and spin coating are popular routes to the formation of high quality, dense, crack free, insulating films. However, the electrical properties of the films are often different than those measured for bulk specimens of the same composition. Pb(Zr0.53Ti0.47)O3 films were deposited from a 2-methoxyethanol based sol–gel system onto Pt/Ti/SiO2//Si substrates via spin-casting. Multiple layers were s ◦

Direct current field adjustable ferroelectric behaviour in (Pb, Nb)(Zr, Sn, Ti)O3 antiferroelectric thin films
Abstract (Pb,Nb)(Zr,Sn,Ti)O3 antiferroelectric (AFE) thin films have been fabricated on LaNiO3/Pt/Ti/SiO2/Si wafers using a sol–gel process. The electric field-induced antiferroelectric-to-ferroelectric (AFE–FE) phase transformation behaviour and its dependence on the temperature were examined by investigating the dielectric constant and dielectric loss versus temperature and electrical field. ...
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 ...
متن کاملCOMPOSITION DEPENDENCE OF MECHANICAL AND PIEZOELECTRIC PROPERTIES OF PULSED LASER DEPOSITED Pb(Zr,Ti)O3 THIN FILMS
In this contribution we present the compositional dependence of the longitudinal piezoelectric coefficient (d33,f), residual stress and Young’s modulus of Pb(Zrx,Ti1−x)O3 (PZT) thin films. Pulsed laser deposition (PLD) was used to deposit epitaxial PZT thin films with a < 110 > preferred orientation on silicon cantilevers. By using PLD, excellent piezoelectric properties of the PZT were observe...

متن کاملStress effects in sol-gel derived ferroelectric thin films
Residual stress development during processing of sol-gel derived ferroelectric thin films influences electromechanical properties and performance. The present work investigates the effects of stress on field-induced polarization switching in ferroelectric Pb~Zr0.52Ti0.48)O3 ~PZT! ~52/48! thin films. Film response is measured as a function of externally applied mechanical stress using a double-b...
