Abstract
An ablation plasma generated by intense, pulsed ion beam was used for thin-film deposition of commercially interesting material (Bax ,Sr1-x)TiO3 (0<x<1). The deposition has been carried out in vacuum and on the substrate at the room temperature. The deposited thin films were analyzed by using Rutherford backward scattering, X-ray photoelectron spectroscopy, atomic force microscope and scanning electron microscopy. It has been understood that the film deposition rate was ~20 nm/shot and the thin film had the same composition as the target. Maximum dielectric constant was obtained at x=0.5
