The effect of mole concentrations of Sr-doped of Ba_(1-X)Sr_xTiO_3 film on microstructure, optical, and electrical properties

摘要

The growth of Ba_(1-x)Sr_xTiO_3 ferroelectric film has been successfully doped using mole variations of Sr-doped with the percentage of 1%, 3%, 5%, and 10%. Variations were made to determine the effect of Sr-doped mole concentrations on the microstructure, optical properties, and electrical properties of the coating applied to the photovoltaic effect. The deposition of the film was done using the Chemical Solution Deposition (CSD) method that was prepared using the spin coating technique. The film was characterized using UV-Vis, X-Ray Diffraction (XRD), and I-V meters. The results showed that the greater concentration of Sr-doped made the crystallite size and resulted in the smaller percentage of transmittance. The transmittance value of Ba_(1-x)Sr_xTiO_3 film at all concentrations increased when the wavelength was 320 nm to 800 nm. The transmittance value < 50% means that the film has made the ability to absorb the light. I-V graph shifted in dark and light conditions when it was given a voltage so that it formed a diode graph.
