    Abstract

    Single phase thin films of (Ba0.5Sr0.5)TiO 3 have been prepared by single target RF magnetron sputtering. Through post-annealing process in box furnace at 1100°C for 1 h, we have been able to improve the dielectric properties; dielectric permittivity, dielectric loss, and tunability. The change in dielectric properties before and after post-annealing is attributed to the change in film strain and the contraction in film lattice.
