(
x
= 0.1, 0.2) thin films for potential application in microwave technologies were prepared by chemical solution deposition method on Pt-coated silicon substrates and sintered at different temperatures. The prepared films were examined by SEM, AFM, XRD and Raman spectroscopy in order to study the influence of dopants on microstructure and phase changes. Dielectric and ferroelectric properties of the doped BaTiO

thin films were also investigated to find the optimal composition and structure for tunable application. Complex shaped silver electrodes suitable for measurements of tunability at GHz frequencies were prepared by inkjet printing method. The electrodes with circular shape were printed on the surface of BaTiO

based thin films by Dimatix inkjet printer. Precision limits of the method and the influence of printing conditions on electrode size and quality were also investigated. |
