摘要：
In this work the effect of Ca doping on the structural and electrical properties of BaTiO3 thin films prepared by sol-gel method was investigated. The XRD patterns revealed the perovskite structure of BCT thin film shows tetragonality decreases with increase of Ca concentration at Ba-site. AFM images show dense, homogeneous and smooth micrograph of these thin films. The dielectric measurements of thin films show that dielectric constant decreases with Ca substitution. Polarization study shows the ferroelectric character of BCT thin films which decreases with increase in the concentration of Ca content on barium titanate.
