| Summary: | The present study is devoted to synthesis and investigation of basic properties of ferroelectric
thin films. The sol-gel-type chemical solution deposition method was used for preparation
of (Ba$_{0.6}$Sr$_{0.4}$)TiO$_{3}$ (BST) thin films. The thin films were characterized in terms of
their microstructure, crystalline structure, chemical composition and dielectric properties. It
was found that the BST thin films adopted cubic crystallographic symmetry of the space
group $Pm3m$, whereas the chemical composition of the thin films corresponded well with the
chemical composition of the solution. Complex impedance spectroscopy was used to measure
frequency-dependent dielectric properties of the thin films. Due to the high tunability and
low dielectric loss, great application potential of these ferroelectric thin films was considered
especially as tunable dielectric devices. |
